If sin(θ) = 0.866, what is θ? (2022)
Steps
Concepts
Step 1: Understand that sin(θ) represents the sine of an angle θ.
Step 2: Know that sin(60°) is a common value in trigonometry.
Step 3: Recall that sin(60°) equals √3/2.
Step 4: Calculate the approximate value of √3/2, which is about 0.866.
Step 5: Since sin(θ) = 0.866, we can conclude that θ must be 60°.
Trigonometric Functions
– Understanding the sine function and its values for common angles.
Inverse Trigonometric Functions
– Using the inverse sine function to find angles from sine values.
