The rectangular coordinates of (6,pi/4)(6,π4) is 3(sqrt(2),sqrt(2))3(2,2)

Explanation:

Given the polar coordinates (r,theta)=(6,pi/4) (r,θ)=(6,π4)
Find the rectangular coordinates (x,y)(x,y)
x=rcostheta; y=sinthetax=rcosθ;y=sinθ where r=6r=6 and theta = pi/4θ=π4
x=6cos(pi/4)=3sqrt(2); y=6sin(pi/4)=3sqrt(2)x=6cos(π4)=32;y=6sin(π4)=32
Hence (x,y) = (sqrt(2),sqrt(2))(x,y)=(2,2)
