Question

Differentiate
F(x)=3x^2 - 2cosx

Answer 1

6x + 2sinx. do you need the working?

Answer 2

yes please

Answer 3

3x^2 becomes 6x cause you bring down the power and subtract the original by 1 (it's a bit weird typing it out i hope you understand). so essentially it's like (2)3^(2-1) which gives you 6^1...

for the second one, when you differentiate cosf(x) you get -f'(x)sinf(x), so f'(x) of -2cosx will give you -2(-1)sinx = +2sinx and then you combine everything n you get 6 + 2sinx.

Answer 4

can you visualise it? typing math out is hard hahaha
