## Calculus (3rd Edition)

$\sin{\theta} = \dfrac{8}{17}$ $\cos{\theta} =\dfrac{15}{17}$ $\tan{\theta}=\dfrac{8}{15}$ $\csc{\theta}=\dfrac{17}{8}$ $\sec{\theta} =\dfrac{17}{15}$ $\cot{\theta}=\dfrac{15}{8}$
Recall: $$\sin{\theta} = \dfrac{\text{opposite}}{\text{hypotenuse}}$$ $$\cos{\theta} = \dfrac{\text{adjacent}}{\text{hypotenuse}}$$ $\sin{\theta} = \dfrac{\text{opposite}}{\text{hypotenuse}} = \dfrac{8}{17}$ $\cos{\theta} = \dfrac{\text{adjacent}}{\text{hypotenuse}} = \dfrac{15}{17}$ $\tan{\theta}= \dfrac{\sin{\theta}}{\cos{\theta}} = \dfrac{8}{15}$ $\csc{\theta}= \dfrac{1}{\sin{\theta}} = \dfrac{17}{8}$ $\sec{\theta} = \dfrac{1}{\cos{\theta}} = \dfrac{17}{15}$ $\cot{\theta}=\dfrac{1}{\tan{\theta}}= \dfrac{15}{8}$
