Convert the complex number $z=\(\sqrt\)2\(\left\)(\(\cos\]\frac{7\pi}{4}\)+i・\(\sin\[\frac{7\pi}{4}\]\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 + 4i

In Exercises 27–36, write each complex number in rectangular form. If necessary, round to the nearest tenth. 6(cos 30° + i sin 30°)

In Exercises 27–36, write each complex number in rectangular form. If necessary, round to the nearest tenth. 8(cos 7π/4 + i sin 7π/4)

In Exercises 27–36, write each complex number in rectangular form. If necessary, round to the nearest tenth. 20(cos 205° + i sin 205°)
