Ive been trying to solve but im not succeeding, can someone please tell me what equation to use and how to solve?

If an electron is confined to a one-dimensional box 200 pm in length, calculate the zero-point energy.

1. 1.51 × 10−18 J

2. 1.51 × 10−20 J

3. 1.21 × 10−19 J

4. 6.04 × 10−18 J

how do you find the critical points for f(x)= e^x?

I have to find the interval on which the given function f increases and on which interval f decreseas

for example, i want to write something like my eyes were getting watery when i looked at a photograph..but i want to make it sound more emotional or interesting..

im not sure how to do this problem...

how do i solve for finding the limit of x approaching 0 when (x) / |x|
