Intro AAB ECE 30 Lecture 1.22 Exercise Set Do these problems individually, but check your answers as a pair. (Pairs to be-assigned-in-class-signature-required) 1 Find the angle. . for the number: x = 1+15 j 2 Find the magnitude of the complex number x above. 3 Write x in the form r ele; i.e., write it in polar form (by hand). 4 Change to polar form: y 5 + 12] (write the answer by hand.) 5 Change to Cartesian Coordinates: 2e i60 Watch the units! 6. Change to Cartesian Coordinates: 4 e 2 7. Simplify: (4+j)/(5-2j), and write the answer in polar and rectangular form. (Again, write the polar form answer by hand.) Simplify: (4+2) (2+ 5i), and write the answer in polar and rectangular form. (Again, write the polar form answer by hand.) 8 Lecture 09 Intro, to MATLAB Lect-0
