Solve for x tan(x)=2

Problem

tan(x)=2

Solution

1. Identify the equation as a basic trigonometric equation where the tangent of an unknown angle x is equal to a constant.

2. Apply the inverse tangent function to both sides of the equation to find the principal value of x

x=arctan(2)

3. Determine the general solution by accounting for the period of the tangent function, which is π

x=arctan(2)+n*π

4. Specify the domain for the integer constant n which represents any integer.

n∈ℤ

Final Answer

tan(x)=2⇒x=arctan(2)+n*π,n∈ℤ
