you look sec^2 up in the formula book (it should be there) then you need to do the product rule. and that should give you an answer -i hope-

or possibly the chain rule thing I think it is

No isn't in the formula book, only the integral of it - tanx

If you have any function, then adding a constant within that function (if you know what I mean) doesn't make any difference. For example: (c is a constant)

In general, if , then . You can apply this logic to the differentiation you're trying to do.

If you're stuck on differentiating sec^2 x, then use chain rule, the derivative of sec x is in the formula book.

Have you managed to differentiate?

The derivative of secx is secx tanx. Use the chain rule.

To integrate, is the derivative of tanx... (it's in the formula book)

yup remember sec^2 = (cos x)^-2
