I just can't grasp it, I'm too stupid and don't understand. pls halp, don't give me the solution but help me understand.

For instance let's take a look at this exercise:

Demonstrate that for any natural number equal or higher than 2 this is true:

(1 - 1/4) , (1 - 1/9), (1 - 1/16)... (1 - 1/n^2) = (n + 1)/2n

## First step, (base). Prove that it is true with n = 2.

1 - 1(2^2) = (2 + 1/2n) => 1 - 1/4 = 3/4 => 3/4 = 3/4

## Second step, hypothesis, n = k, then k + 1

(1 - 1/(k+1)^2) = ((k+1) + 1)/2(k+1)
1 - 1/(k^2 + 2k + 4) = ((k+1)+1)/2k + 2

wat now?

How does this make you feel, /sci/?

Hey /sci/ i actually have a serious math question. Im not trolling.

For multivariable calculus, specifically in the area of double and triple integration how does one derive the integrand. I know in single variable the integrand is just the derivative, however with multi i feel like there is a different method. Thanks alot.
