parametric equations

Question 1

how to perform differentiation with parametric equations (parametric differentiation)

Answer 1

• work out dx/dt and dy/dt
• multiply dy/dt by dt/dx to get dy/dx in terms of t

Question 2

Answer 2

• work out dx/dt
• integrate the product of y and dx/dt to find integral in terms of t

Question 3

how to perform integration with parametric equations

Answer 3

• work out dx/dt
• integrate the product of y and dx/dt to find integral in terms of t
