Polar Coordinates and Complex Numbers
The purpose of this assessment is to help you determine whether you have a clear understanding of polar coordinates and complex numbers.
Solve the following problems
1. The rectangular coordinates of a point are given. Find the polar coordinates of the point. Express θ in radians. (-5, 5)
2. Plot the complex number. z = 4 + 5i
3. Find the absolute value of the complex number. z = 14i
4. Write the complex number in polar form. Express the argument in degrees. z = 5i
