Q:
Write the complex number in polar form. express the argument in degrees, rounded to the nearest tenth, if necessary. 5) 2 +2i
Accepted Solution
A:
Here you need to calculate the magnitude and phase angle of the quantity 2 + 2i.
The magnitude is found using the Pyth. Thm. and is sqrt(2^2 + 2^2), or [tex] \sqrt{8} [/tex], or 2[tex] \sqrt{2} [/tex]
Recognize that the phase angle is 45 deg, or [tex] \pi [/tex]/4 rad.
Thus, the complex form is (2sqrt(2) angle [tex] \pi [/tex]/4 rad ).
