mulitiply both sides of this equation by r and use the fact that r2=x2+y2 to rewrite this equation in terms of x and y r=-6sin t
tensa zangetsu [6.8K]

The equation in terms of the x and y will be 216Sin³\theta = 6x²Sin\theta  + 6y²Sin\theta.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The value of the expression will be given as:-

r³ = r(x² + y²)

( 6Sin\theta)³ = 6Sin\theta (x² + y²)

216Sin³\theta = 6x²Sin\theta + 6y²Sin\theta

Therefore the equation in terms of the x and y will be 216Sin³\theta = 6x²Sin\theta  + 6y²Sin\theta.
