If I am given a right triangle with legs 12 and 5, and a hypotenuse of 13, how to I find the complex number of e^(i*theta) in standard form a+bi? Theta represents the larger acute angle in this triangle. I don't understand because when I did tan^-1(12/5) on my calculator in radians, I get 1.176. But that's not right because it can't be made into a precise fraction and I have no idea how to put it in complex standard form
