Differentiate with respect to x:cot2 x

1.	Differentiate with respect to x:cot2 x
Answer» Chain rule: If y = f(t) and t = g(x) then dy/dx = dy/dt x dt/dx Let y = cot² x dy/dx = – 2cot x [d/dx (cotx)] = – 2 cot x cosec²x

Answer»

Chain rule:

If y = f(t) and t = g(x) then dy/dx = dy/dt x dt/dx

Let y = cot² x

dy/dx = – 2cot x [d/dx (cotx)]

= – 2 cot x cosec²x
