How do you find the derivative of # y =10sinx+100#? Calculus Differentiating Trigonometric Functions Derivatives of y=sec(x), y=cot(x), y= csc(x) 1 Answer Matt B. Dec 8, 2016 We can look at your function as: #y=cf(x)+b# Where #c# and #b# are constants. Thus: #y'=cf'(x)+0# So: #y'=10cosx# Answer link Related questions What is Derivatives of #y=sec(x)# ?
