Questions & Step-by-Step Solutions
Find the value of cos^(-1)(0).
Correct Answer: π/2
Steps
Concepts
Step 1: Understand what cos^(-1)(0) means. It is asking for the angle whose cosine value is 0.
Step 2: Recall the unit circle, which helps us understand the values of cosine for different angles.
Step 3: Identify the angle where the cosine value is 0. This occurs at π/2 radians (90 degrees).
Step 4: Confirm that cos(π/2) = 0, which means cos^(-1)(0) = π/2.
Inverse Trigonometric Functions
– Understanding how to find angles using inverse functions, specifically the cosine function.
Unit Circle
– Knowledge of the unit circle and the values of trigonometric functions at key angles.
