Complex conjugate of cos

http://www.cchem.berkeley.edu/chem120a/extra/complex_numbers.pdf WebComplex Conjugate in Trigonometric form. z ¯ = r ( cos ( − θ) + i sin ( − θ)). Say z is a complex number a + b i. Then, its trigonometric form is. And z ¯ is the complex conjugate of z. Then z ¯ is equivalent to a − b i and its trigonometric form is. I got stuck at this point.
