How do you differentiate #t^2sint#? Calculus Differentiating Trigonometric Functions Differentiating sin(x) from First Principles 1 Answer Gió Jul 20, 2015 I found: #t[2sin(t)+tcos(t)]# Explanation: I would use the Product Rule to get: #f'(t)=2tsin(t)+t^2cos(t)=t[2sin(t)+tcos(t)]# Answer link Related questions How do you differentiate #f(x)=sin(x)# from first principles?
