Question

Is the value of cosA = $\frac{5}{4}$ true for some angle A?. State whether true or false.

• A. True
• B. False

Answer 1

The correct option is B

False

The value of the trigonometric ratio, cosine, is always between [-1, 1], it can never be greater than 1. So the above statement is false as $\frac{5}{4}$ is greater than 1.
