How do you integrate #secx^2/(1+tanx^2 )dx#?

Answer 1

The answer is #=x+C#

Let's do some simplification

#sin^2x+cos^2x=1#
Dividing by #cos^2x#
#sin^2x/cos^2x+1=1/cos^2x#
#tan^2x+1 =sec^2x#

So,

#int(sec^2xdx)/(1+tan^2x)#
#=int1*dx#
#=x+C#

To integrate sec^2(x) / (1 + tan^2(x)) dx, you can use trigonometric identities to simplify the expression. Start by expressing sec^2(x) in terms of sin(x) and cos(x), and tan^2(x) as well. Then, simplify the expression and integrate term by term. The integral of sec^2(x) / (1 + tan^2(x)) dx simplifies to the integral of cos(x) dx. Therefore, the result of the integration is sin(x) + C, where C is the constant of integration.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
