Explain your answer and i'll mark the brainliest!
convert the polar representation of this complex number into its rectangular form:
z = 7(cos π/2 + i sin π/2)

a. (-7, 0)

b. (0, -7)

c. (7√ 3, 0)

d. (0, 7)

solution given:

z = 7(cos π/2 + i sin π/2)

z=7(0+1i)=7i

So in rectangular form:(0,7)

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
