Question

Question 2: If x and y are connected parametrically by the equation, without eliminating the parameter, find. x = a cos θ, y = b cos θ

Class 12 - Math - Continuity and Differentiability

Answer 1

x = a cos θ, y = b cos θ

dy/dθ = -bsinθ
dx/dθ = -asinθ

dy/dx = (dy/dθ) /(dx/dθ)
= -bsinθ/-asinθ = b/a
