How do you find the angle of a number?

Divide the number of minutes by 60 and add to the number of degrees. So, for example, 12° 28' is 12 + 28/60 which equals 12.467°. Next multiply by π and divide by 180 to get the angle in radians.

How do you find the angle of a complex fraction?

If z=a+bj where a and b are real, then you can determine the phase angle as arctan(ba) (as long as you are careful about the signs and quadrants), since a+bj represents a point in the complex plane, and the phase angle is the angle this vector makes with the x-axis.

How do you find the angle in complex polar form?

To write complex numbers in polar form, we use the formulas x=rcosθ, y=rsinθ, and r=√x2+y2. Then, z=r(cosθ+isinθ).

What is a complex angle?

These two arcs expressed as a percentage of the radius represent circular and hyperbolic angles, respectively, and being in quadrature with each other their vector sum is the “complex” angle of the arc.
