Use de moivre's theorem to write the complex number in trigonometric form: (cos(3pi/12) + i sin (3pi/12))^5
a) cos(15 pi/12) + isin (15pi/12)
b) 5(cos(3 pi/12) + isin (3 pi/12)
c) cos (3pi/60) + isin (3pi/60)
d) cos (3pi/12)^5+i sin (3pi/12)^5

There are many types of numbers in mathematics such as :

Complex Number consist of Real Number and Imaginary Number and can be expressed as :

The absolute value of complex number is also called Modulus and can be calculated using this formula :

Let us tackle the problem.

De Moivre's formula for complex numbers is as follows :

Using the formula above, we can solve the problem in the following way

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
