Hello, here I worked a problem out and got a different answer than the book gave so I was wondering if it looks correct or not.

Thanks for the help

You could always try plugging in a few values for x to see...

Anyways... does

$$\frac{1}{1 + 1} = \frac{1}{1} + \frac{1}{1}$$

?

integral(cscx*sec^2(x)dx) does not equal the original integral.

1/(1-cos^2(x)) does not equal 1/cos^2(x)
you probably overlooked the one.
