Please help :c

the first word is find

The values of and are 2 and 150º.

Step-by-step explanation:

The complete statement is:

Find and such that  .

We proceed to use the following trigonometric identity:

(1)

By direct comparison we derive these expressions:

(2)

(3)

By dividing (2) by (3), we have the following formula:

The tangent function is negative at second and fourth quadrants. That is:

There are at least two solutions:

,

And the value of :

The values of and are 2 and 150º.

correct answer:

i^31 = -i
