Polar form of a complex number solutions

  Polar form of a complex number. If z= x + iy is a complex number. Then z = r ( cosθ + sinθ ) is called polar form or trigonometric form of a complex number.   By comparing real and imaginary parts of a complex number,  we get x = r cosθ           (1) y = r sinθ  …
