Answer 2

Solving the Equation Cos(3x-π/3) = -1

To solve the equation cos(3x-π/3) = -1, we can use trigonometric properties and algebraic manipulation to find the value of x that satisfies the equation.

First, let's recall the property of cosine function: - cosine(x) = -1 when x = (2n+1)π, where n is an integer.

Now, let's apply this property to the given equation.

The equation cos(3x-π/3) = -1 implies that 3x-π/3 = (2n+1)π for some integer n.

By solving for x, we get: 3x = (2n+1)π + π/3 x = ((2n+1)π + π/3)/3

This gives us the general solution for x in terms of n.

Let's verify this solution with a specific value of n to find a particular solution for x.
