sin x=frac35\*Rightarrow csc x=frac1sin xRightarrow csc x= frac53\*Rightarrow cos^2 x+sin^2 x=1Rightarrow cos^2 x=1-frac925=frac1625\*Rightarrow cos x=frac45\* Rightarrow an x=fracsin xcos x=fracfrac35frac45\*Rightarrow an x= frac34\*Rightarrow cot x=frac1 an xRightarrow cot x=frac43\*sec x=frac1cos xRightarrow sec x=frac54\*
