tan t = $\frac{8}{15}$ csc t = $\frac{17}{8}$ sec t =$\frac{17}{15}$ cot t = $\frac{15}{8}$

Work Step by Step

tan t is computed by $\frac{sin t}{cos t}$ tan t = $\frac{sin t}{cos t}$ =$\frac{\frac{8}{17}}{\frac{15}{17}}$ =$\frac{8}{15}$ csc t = $\frac{1}{sin t}$ = $\frac{1}{\frac{8}{17}}$ = $\frac{17}{8}$ sec t = $\frac{1}{cos t}$ = $\frac{1}{\frac{15}{17}}$ = $\frac{17}{15}$ cot t = $\frac{1}{tan t}$ = $\frac{1}{\frac{8}{15}}$ = $\frac{15}{8}$
