Write each expression in terms of sines and/or cosines and then simplify.

(cot(z))/(csc(z)) =

(cos(z))/(sec(z)) + cos^2(z) =

(1)/(sin^2(z)) - (1)/(tan^2(z)) =

Write each expression in terms of sines and/or cosines and then simplify. (cot(x))/(csc(x))= (cos(x))/(sec(x))+cos^(2)(x)= (1)/(sin^(2)(x))-(1)/(tan^(2)(x))= Write each expression in terms of sines and/or cosines and then simplify cot(z) cos(z) csc(z) cos(z) + cos^2(z) = sec(z) - 1/sin^2(z) - 1/tan^2(z)
