To solve the equation 2 cos-1 x = π, we can follow these steps:

Step 1: Isolate the Inverse Cosine

First, divide both sides of the equation by 2:

cos-1 x = π/2

Step 2: Apply the Cosine Function

Next, we take the cosine of both sides to eliminate the inverse cosine:

x = cos(π/2)

Step 3: Calculate the Cosine Value

The cosine of π/2 is 0:

x = 0

Final Answer

The solution to the equation 2 cos-1 x = π is:

  • x = 0
