## anonymous 3 years ago Prove that 1+sec^2x*sin^2x=sec^2x

1. geerky42

Remember, $$\sec^2x = \dfrac{1}{\cos^2 x}$$

How does that help me?

3. geerky42

Replace it then simplify. You will see what I mean.

4. geerky42

in 1+sec^2x*sin^2x, of course.

I got it, sorry for not reporting back to you.
