Question

Find the following integrals:

`int(sec^2x)/(cosec^2x) dx`

Sum
Advertisements

Solution

Let `I = int (sec^2 x)/(cosec^2)  dx`

`I = int (1/(cos^2 x))/(1/(sin^2 x))  dx`

`I = int (sin^2 x)/(cos^2 x)` dx

`I = int tan^2 x  dx`

`I = int sec^2 x - 1  dx`

`I = int sec^2 x  dx - int 1  dx`

I = tan x - x + C
