Find the Cartesian coordinates of the given polar coordinates

(a)    (5, π)

b. (4, −2π/3)
c. (−4, 3π/4)

a. (-5,0)

b. (-2,-2(3)^0.5)

c. (2(2)^0.5,-2(2)^0.5)................................................................................................................................................

I do not understand your answers for b and c. Please explain or give exact numbers for coordinates

b. x component=4*cos(−2π/3), y component=4*sin(−2π/3)

c. x component=-4*cos(3π/4), y component=-4*sin(3π/4)

That does not work for my work. I need it to be numbers.

b. x component=4*cos(−2π/3)=-2, y component=4*sin(−2π/3)=-2*(3)^0.5

c. x component=-4*cos(3π/4)=2(2)^0.5, y component=-4*sin(3π/4)=-2(2)^0.5

if you don't understand my answer you can calculate it yourself, I already gave you the steps to calculate them. Remember to set the calculator into radian mode.
