Question

The value pi/24 is a solution for the equation 4 cos^4 (4x)-3

Answer 1

THE ANSWER IS TRUE.

Explanation:

I did this on my homework.

Answer 2

False

Explanation:

4 cos^4 (4x)-3 = 0

Substitute into the equation

4 cos^4 (4pi/24)-3 = 0

4 cos^4 (pi/6)-3 = 0

Take the cos pi/6

4 ( sqrt(3)/2) ^4 -3 =0

Take it to the 4th power

4 ( 9/16) -3 =0

9/4 -3 =0

9/4 - 12/4 = 0

-3/4 =0

False
