Find an antiderivative. http://www.webassign.net/www31/symIm...b5e40f147d.gif

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

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

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

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

Do you remember anything whose derivative is equal to $\displaystyle \sec^2 t$ ;)? - Feb 8th 2009, 11:18 PMVkL
Tan(t) ? haha
