If tan(θ) = 1, what is the value of θ? (2020)
Steps
Concepts
Step 1: Understand that tan(θ) represents the tangent of an angle θ.
Step 2: Recall that the tangent function is defined as the ratio of the opposite side to the adjacent side in a right triangle.
Step 3: Know that tan(45°) equals 1 because in a 45°-45°-90° triangle, the opposite and adjacent sides are equal.
Step 4: Since tan(θ) = 1, we can conclude that θ must be 45°.
Trigonometric Functions
– Understanding the tangent function and its values at specific angles.
Inverse Trigonometric Functions
– Recognizing that multiple angles can yield the same tangent value due to periodicity.
