tan t = $\frac{3}{4}$ csc t = $\frac{5}{3}$ sec t = $\frac{5}{4}$ cot t = $\frac{4}{3}$

Work Step by Step

tan t is computed by $\frac{sin t}{cos t}$ tan t = $\frac{sin t}{cos t}$ =$\frac{\frac{3}{5}}{\frac{4}{5}}$ =$\frac{3}{4}$ csc t = $\frac{1}{sin t}$ = $\frac{1}{\frac{3}{5}}$ = $\frac{5}{3}$ sec t = $\frac{1}{cos t}$ = $\frac{1}{\frac{4}{5}}$ = $\frac{5}{4}$ cot t = $\frac{1}{tan t}$ = $\frac{1}{\frac{3}{4}}$ = $\frac{4}{3}$
