Simplify tan(405)
Problem
Solution
Identify the periodicity of the tangent function. The tangent function has a period of
180 meaningtan(θ+180⋅k)=tan(θ) for any integerk Subtract multiples of
180 from the angle to find a coterminal angle within a standard range.
Evaluate the tangent of the resulting angle using the unit circle or trigonometric identities.
