# Math Help - Find the Anti-derivative (NEED HELP ASAP)

1. ## Find the Anti-derivative (NEED HELP ASAP)

Find an antiderivative.

How do you integrate ( 1 / [(cos ^ 2) t]) ??

The
antiderivative of Cos(t) = sine(t), then I am lost. Help please!

2. Recall that: $\frac{1}{\cos x} = \sec x$

So you have: $\int p(t) dt = \int \left(\cos t + \sec^2 t\right) dt$

Do you remember anything whose derivative is equal to $\sec^2 t$ ?

3. Tan(t) ? haha
