in the trigonometric form r(cos + i. are given by the following formula. ( ) rn. cos 360 k + n n. + i sin 360 k + n n ; f or k = 0; 1; 2; :::; n 1: example we need to write 4 in trigonom. tric form by using:= p(a)2 + (b)2 and = arg(z. So we have the complex number a + ib = 4 + i0. Therefore a = 4 and b = 0.
