Convert the equation in rectangular coordinates x y given be

Convert the equation in rectangular coordinates (x, y) given below into an equation in polar coordinates (r, ).

x=-3

Convert the equation in polar coordinates (r, ) given below into an equation in rectangular coordinates (x, y).

=11 / 3

Solution

x = -3, y = 0

Then ========> r = 3, = 0

b) =11 / 3

x = r*cos = 0.5 r

y = rsin = -0.866 r
