# Verify by differentiation that the formula is correct. ∫ tan 2 x   d x = tan x − x + C

To determine

To verify:

tan2x dx=tanx-x+C

Explanation

Solution:

tan2x dx=tanx-x+C

1)  Concept:

ddxf(x)dx=fx

2) Formula:

sec2x-1=tan2x

3) Calculation:

Consider,

tan x-x+C

Taking derivative with respect to x and applying differentiation of trigonometric functions,

ddx<
