The feel

did that guy ever solve the limit problem?

it's me here

here's what I'm confused about

when I'm given a limit problem like
>4 Cos x
and the limit x-> c
>c=pi/3
and I find pi/3 is equal to 1/2 per the unit circle, how come it's not 1/2 * 4 is the final answer, but rather just 1/2 is the final answer?

shit nevermind that was a bad example because 4pi/3 is equal to -1/2

I taught myself Trigonometry, Summation, and Fourier Series in the senior year of high school with Desmos. Do not underestimate this thing.

thats bizzare, I would have to see the problem as it was written out.

keep posting more if you want

this answer is wrong,

why?

delta x goes to zero so the limit is -4

the answer was 2x-6

how about this one?

6x is continuous, cos(x) is continuous, so there is none.
