1 + sec^2x sin^2x = sec^2x please help verify the equation so the left side is equal to the right
One side is expressed as two terms where the other side is expressed as one. So first step is to write those two terms as one term. So first you could wright in terms of sin and cos if you like.
So you have what on the left hand side if you do that.
i dont know how to do that
so you don't know how to write sec in terms of cos?
