Question

How to draw the graph of sec²x

Answer 1

Step-by-step explanation:

I want to found a solution for the following integral :

S sec²x/(tan²x +2tanx + 2) dx

I thought I was already a step furhter by changing it to :

S sec²x/((tanx + 1)² + 1) dx

Now the derivative of 1/(tanx +1) = -1* (1/(tanx +1)²) * (1/cos²x) = -1

* (1/tanx + 1)² * (sec²x)
