How do you differentiate the following parametric equation: # (3sin(t/6-pi/12), 2tcos(pi/3-t/8))#? Calculus Parametric Functions Derivative of Parametric Functions 1 Answer Pankaj Solanki Sep 18, 2017 #dx/dt=1/2 cos(t/6-pi/12)# #dy/dt=2{cos(pi/3-t/8)+t/8sin(pi/3-t/8)}# Explanation: #x=3sin(t/6-pi/12)# #dx/dt=3(1/6)cos(t/6-pi/12)=1/2 cos(t/6-pi/12)# #y=2tcos(pi/3-t/8)# #dy/dt=2{cos(pi/3-t/8)d/dt(t)+td/dt(cos(pi/3-t/8)}# #dy/dt=2{cos(pi/3-t/8)*(1)-t(-1/8)sin(pi/3-t/8)}# #dy/dt=2{cos(pi/3-t/8)+t/8sin(pi/3-t/8)}# Answer link Related questions How do you find the second derivative of a parametric function?
