How do you differentiate #s=(1+sint)/(1+cost)#? Calculus Basic Differentiation Rules Quotient Rule 1 Answer Andrea S. Feb 27, 2017 #(ds)/(dt) = ( 1+ cost + sint)/(1+cost)^2# Explanation: Using the quotient rule: #(ds)/(dt) = ( (1+cost) d/(dt) (1+sint) - (1+sint) d/(dt) (1+cost))/(1+cost)^2# #(ds)/(dt) = ( (1+cost) cost + (1+sint) sint)/(1+cost)^2# #(ds)/(dt) = ( cost+cos^2t + sint+sin^2t)/(1+cost)^2# #(ds)/(dt) = ( 1+ cost + sint)/(1+cost)^2# Answer link Related questions What is the Quotient Rule for derivatives?
