How do you differentiate #f(x)=2cscx+5cosx#? Calculus Differentiating Trigonometric Functions Derivatives of y=sec(x), y=cot(x), y= csc(x) 1 Answer Tazwar Sikder May 20, 2017 #f'(x) = - 2 csc(x) cot(x) - 5 sin(x)# Explanation: We have: #f(x) = 2 csc(x) + 5 cos(x)# #Rightarrow f'(x) = frac(d)(dx)(2 csc(x)) + frac(d)(dx)(5 cos(x))# #Rightarrow f'(x) = 2 (- csc(x) cot(x)) + 5 (- sin(x))# #Rightarrow f'(x) = - 2 csc(x) cot(x) - 5 sin(x)# Answer link Related questions What is Derivatives of #y=sec(x)# ?
