Transcript text: Find values of the trigonometric functions of the angle (in standard position) whose terminal side passes through the given point.
$(24,7)$
$\sin \theta=\frac{7}{25}$
$\cos \theta=$ $\square$
Solution
Solution Steps
Step 1: Calculate the radius \(r\)
The radius \(r\) is calculated using the Pythagorean theorem: \(r = \sqrt{24^2 + 7^2} = 25\).
Step 2: Calculate the trigonometric functions
Using the definitions of trigonometric ratios in a right-angled triangle, we find:
\(\sin \theta = \frac{y}{r} = 0.28\)
\(\cos \theta = \frac{x}{r} = 0.96\)
\( an \theta = \frac{y}{x} = 0.29\) if \(x \neq 0\).
Step 3: Calculate the reciprocal trigonometric functions
For the reciprocal trigonometric functions, we find:
