How to determine angles and degrees
WebTake the cos of the angle and multiply it by the magnitude to get the x value (rounding it to the nearest thousandth) and use sin for the y value but do the same thing. Example: A complex number z₁ has a magnitude z₁ = 20 and angle θ₁ = 281° Express z₁ in rectangular form, as z₁ = a + bi. Round a and b to the nearest thousandth.

All you have to do is follow these steps: Choose your initial angle — for example, 610°. If your angle is larger than 360° (a full angle), subtract 360°. Keep doing it until you get an angle smaller than a full angle. This is the same as finding the modulo.
