What is inverse sine, cosine, and tangent?

Problem Statement

What is inverse sine, cosine, and tangent?

Step-by-Step Explanation

Inverse trig functions work backward from a ratio to an angle, with restricted ranges so each answer is unique.

1. Identify what the question is asking. In Trigonometry, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
3. Work one step at a time and keep units, signs, and restrictions visible.
4. Check whether the answer makes sense in the original context.

Final Answer

Inverse trig functions work backward from a ratio to an angle, with restricted ranges so each answer is unique. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
