Question

The parametric equations of the curve x^2/3 + y^2/3 = a^2/3 are ...

(a) x = a sin³θ; y = a cos³θ 

(b) x = a cos³θ; y = a sin³θ 

(c) x = a³ sinθ; y = a³ cosθ 

(d) x = a³ cosθ; y = a³ sinθ

Answer 1

(b) x = a cos³θ; y = a sin³θ

The parametric equations of the curve x^2/3 + y^2/3 = a^2/3 are x = a cos³θ; y = a sin³θ
