Explanation Given: A pair of parametric equations are x = cos 3 t …… ( 1 ) and y = sin 3 t …… ( 2 ) Approach: If f and g are defined on an interval I , then the set of points ( f ( t ) , g ( t ) ) is a plane curve. The equation x = f ( t ) and y = g ( t ) are the parametric equations for the curve, with parameter t ∈ I . Calculation: For every value of t , there will be a point on the curve. If t = 0 , then x = 1 and y = 0 , thus the corresponding point is ( 1 , 0 ) . Some points are determined in the following table ( 1 ) for different values of t . t x y Point ( x , y ) 0 1 0 ( 1 , 0 ) π 2 To determine (b) To find: The rectangular coordinate equation for the curve by eliminating the parameter.
