Write the function in the form y = f(u) and u = g(x). Then find dy/dx as a function of x.y = csc(cot x)
A. y = csc u; u = cot x; 
= csc3 x cot x
B. y = cot u; u = csc x; 
= csc2(csc x) csc x cot x
C. y = csc u; u = cot x; 
= - csc(cot x) cot(cot x)
D. y = csc u; u = cot x; 
= csc(cot x) cot(cot x) csc2 x
