Write the function in the form y = f(u) and u = g(x). Then find dy/dx as a function of x.y = cot(10x - 3)
A. y = cot u; u = 10x - 3; 
= - csc2(10x - 3)
B. y = 10u - 3; u = cot x; 
= - 10 cot x csc2 x
C. y = cot u; u = 10x - 3; 
= - 10 csc2(10x - 3)
D. y = cot u; u = 10x - 3; 
= - 10 cot(10x - 3) csc(10x - 3)
