Question
hello, I need help in trigonometry. For question 19, it is asking to write the standard form of the complex number for part a, and part b is asking to plot the complex number and select one of the answer choices. The first photo shows part a, and the second and third photo shows the graph choices for part b. I hope you can help. thanks so much!
