Question

Find the derivative:
r(x)=Cot (u(x))
s(x)=U(Cot(x))

Answer 1

i believe you have to apply the chain rule

Answer 2

chain rule

Answer 3

\[cotx (dy/dx \cot x)+\cot x(dy/dx \cot x)\]

Answer 4

Answer 5

\[\frac{ d \cot(u(x)) }{ dx }=-cosec^{2}(u(x))*\frac{ du(x) }{ dx }\]

Answer 6

\[\frac{ du(cotx) }{ dx }=u'(cotx)*\frac{ dcotx }{ dx }\]
