There are different types of intelligence, maybe find a different way of thinking about what you're struggling with, a visualization or analogy.
>There are different types of intelligence.
No, there are not. Intelligence is mathematical-logical ability as defined by IQ tests. If OP sucks at that then don't make him believe that twerking or video gaming constitutes another type of intelligence.
That's just incorrect. Someone could hear information and retain none of it, but may do really well reading it. There are autistic savants that can do any math problem you throw at them but can't figure out how to dilate their neovegana without help. I had a teacher with 180 IQ and the guy was a total moron who put shoepolish on his baldspot. Like I said, sometimes it takes a different approach to learning, and suddenly it will just click and it's a breeze going forward, dilating becomes a joy.
>neovegana
Frick you, I am eating and this gave me a mental picture of a worm infested, grotesque, troony axe wound I've seen around /gif/.
No. What you say is correct but manipulative. Intelligent people are able to work things out on their own. What you are describing is a moron with an ability.
You are giving the anon false hope instead of preparing them for the brutality of life.
Many such cases.
Haven’t you got a charity to go to?
>Someone could hear information and retain none of it, but may do really well reading it
That's why you do the exercises in the book after reading. To help you retain the information.
>I had a teacher with 180 IQ and the guy was a total moron who put shoepolish on his baldspot
That doesn't sound moronic to me. The glare from his baldspot can strategically blind students like you.
>Like I said, sometimes it takes a different approach to learning
For math or any kind of acquired skill? You read the book or show up to a lecture, then you immediately start working on exercises. If you can't figure it out, you go look back earlier in the book for a similar kind of problem solved in an example then use that for ideas on how to solve the problem.
You're just repeating yourself
Be a good test taker and problem solver. IQ tests are not absolute. Very low intelligent comment btw.
What topic specifically? matrices?
>A driver sets out on a journey. For the first half of the distance, she drives at the
leisurely pace of 30 mi/h; during the second half she drives 60 mi/h. What is her
average speed on this trip?
She will travel twice the amount of time in the first half since she's going half speed.
These sort of "Gotcha!" gimmicks are exclusive to applied math problems as in your example
Unless you're specifically getting into physics or engineering or something
i didnt get it because it just seems like numbers were pulled from thin air to justify the answer
I know what you mean lol. Sometimes I hear their rationale for a solution and I think "Yeah right, that's a scam."
Don't worry, you didn't get filtered out. Word problems are supposed to be obtuse. Keep doing this until you get used to it, then when you're comfortable with the process you can go back (with a tutor ideally) and try to get a grip on the logic.
I have an average, maybe even below average, intelligence. And I've found that there is no math that I am too dumb to understand. the only reason I get stuck and frustrated sometimes is because they didn't explain it right. If an angel were to descend and granted me the perfect explanation tailor made for me, I would understand absolutely anything. Therefore, in times like these, don't blame yourself, blame the explanation which wasn't good enough. It's also largely a matter of time. I'll bet my mole that if you sat with this problem long enough with a tutor, you would get it. 110%.
(btw in case anyone is curious, the capcha for this post was XH GMX)
A fellow twelver shia i see...
Had a brainfart,
unless you're specifically getting into engineering or physics then a book with just the math and not the any of the moronic real life implications such as worrying about units of measurements, definitions from physics etc.
For the question itself I'm guessing that you're attempting to simply take the average of the two speeds which yields 45 but as the book points out this isn't the scientific definition of average speed.
The numbers he gives (120) are merely to illustrate that if you assume the above definition, you'd get a contradiction.
Regardless, this is a physics problem and not a good measure of your mathematical skill.
How do you do analytic geometry without unit length
Every rigorous book I've read asserts the unit is arbitrary.
Point is, as a mathematician, you're not supposed waste your time worrying about trivial things like conversions.
Still necessary
>applied mathematics is a Gotcha!
LMAO do math majors really
Do you think OP's question is difficult mathematically?
A gimmick is really all an applied question can be since the math used is so shallow.
Wow, so not only is your math ability garbage, you also have shit reading comprehension.
It isn't a "gimmick" it's literally just applied mathematics.
You perceive it as a "gimmick" because you're so busy huffing your own farts with your "pure" mathematics that you totally flounder when an application is presented and you protect your ego by claiming it's a gimmick.
You'd flunk out of engineering in freshman year.
Not the anon you were responding to. But i think you're moronic as frick
>gimmick" it's literally just applied mathematics.
This is exactly the point I was making, it's not mathematics in the traditional sense but something exclusive to applied.
Congratulations moron
>be pure math gay
>smart enough to regurgitate and memorize proofs written by someone else over a century ago
>too dumb for applications
Lol.
>regurgitate and memorize
Lol the projection
>but is this simple minded approach really correct?

45?
You got the firsr answer on the test wrong
this isn't difficult, but it isn't interesting. However, I really enjoy the trig review and proof by induction segments found in Precalculus-not sure if in the text you're reading, but yeah keep studying, its worthwhile.
>What is her
average speed on this trip?
depends on what are you averaging on
why do we assume that the two halves of the trip are equidistant?
is it an unspoken assumption you have to make to use this approach for a solution?
>total distance = 2d
why?
(yes, my IQ is around 100)
Because they are halves, which are by definition equal to each other.
It is a poorly written question, particularly for a starter book, a more mathematically inclined mind might jump to distance as length, but it's just as reasonable to assume time, not to mention someone at precalc has likely never considered arc length rigorously before...
Can someone explain why the numerator and denominator was multiplied by 60?
I'm also going through this book op. Picked it up because wiki told me to.
60 can be divided out by both 60 and 30. 30 then goes into 60 twice, making the 2d. It only goes into itself once, leaving the 1d, totalling to the 120d/3d.
To simplify the complex fraction. 60 because it's the least number that constitutes all the other denominators(30 and 1(remember that n=n/1)).
>I'm getting filtered
You're learning anon
mathematics got easier for me the older i got
Dont give up.
Persistance and hard work beat intelligence and talent. Back when I started with stewart calculus in 2012 I couldnt get them too. Nowdays they are so easy and obvious.
Did you guys take notes when going through this book? Everything is already concise.
Problem sets all day. Do as many as you can and after a while you start getting a feel for how to proceed.
I like to rewrite what I can from memory as a type of study
lmao frick Stewart calc
Problem?
It's a shit book
Why?
Because you need to take a university class in calc to get anything out of it, worthless.
Proof?
Plenty of better calculus textbooks out there anon
Like?
Apostol
Moron
What's the deal? Apostol is one of the best (if not the best) calc books that exist
you need to wrestle with the problem and sit there until you understand it. average iq can understand calculus but will most likely need more time to compute things.
I appreciate this thread OP
I'm self-teaching math and I also got filtered by this same question last week. Im currently a CS student but I already took Calculus and Stats in other studies (Cognitive Science aka Psychology) many years ago
You probably need to practice more
