Express `s inpi/5+i(1-cospi/5)` in polar form.

Express sin(pi)/(5)+i(1-cos(pi)/(5)) in polar form.

Express 1/(1-i) in polar form.

Express (-1+i) in polar form.

Express (1+i)/(1-i) into polar form.

Express (5-3i)^3 in polar form.

Express (1+2i)/(1-3i) in polar form.

Express z=(-1+isqrt(3))/(1+i) in polar form and then find the modulus and argument of z. Hence deduce the value of cos (5pi)/(12)

Express in polar form (1+i)

Express 1 + sqrt(3i) in polar form.
