Question

which trig function is this? sin tan cos

Explanation:

Step1: Recall trigonometric function definitions

In a right - triangle, \(\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}\), \(\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}\), \(\tan\theta=\frac{\text{opposite}}{\text{adjacent}}\). Here, the adjacent side to \(\theta\) is \(8\) and the hypotenuse is \(14\).

Step2: Match with the formula

Since \(\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}\), and we have adjacent \( = 8\) and hypotenuse \(=14\), this is the cosine function.

Answer:

\(\cos\)
