1)Prove that [ cot^2 x ( sec x -1) ] / [1+ sin x] = [sec^2 x ( 1- sin x)] / [1+ sec x] . 2) Show that the function f(x)= ( cos x - sin x) (17 cos x -7 sin x) may be expressed...

Many transformations have equivalent transformations which produce the same graph. For instance, the line f(x)=2x can be translated up 4 units to go g(x)=2x(x+2)=2x+4. For the following equations...
