Question

Solve cos(4x)=1 on the interval [0, π/2] __________.

Options:
A) π/8
B) π/4
C) π/2
D) 0

Answer 1

To solve the equation cos(4x) = 1 on the interval [0, π/2], the value of x that satisfies the equation is x = 0.

Step-by-step explanation:

To solve the equation cos(4x) = 1 on the interval [0, π/2], we need to find the values of x that satisfy the equation. In this case, cos(4x) = 1 when the angle 4x is equal to 0. Since cos(0) = 1, we have 4x = 0. Solving for x, we get x = 0.
