11. Graphing Complex Numbers

Express the complex number $z=7+11i$ in polar form.

Express the complex number $z=2-4i$ in the polar form.

Express the complex number $z=1-\frac{\sqrt{3}}{3}i$ in polar form.

Convert the complex number $z=12\(\left\)(\(\cos\)90\(\degree\)+i・\(\sin\)90\(\degree\]\right\))$ from polar to rectangular form.

Plot each complex number and find its absolute value. z = −3 + 4i

Plot each complex number. Then write the complex number in polar form. You may express the argument in degrees or radians. 2 + 2i

In Exercises 11–26, plot each complex number. Then write the complex number in polar form. You may express the argument in degrees or radians. −4i

In Exercises 11–26, plot each complex number. Then write the complex number in polar form. You may express the argument in degrees or radians. −3
