( x=sqrt{2} operatorname{cosec}^{-1} t quad y=sqrt{2^{sec ^{1} t}} ) ( frac{d x}{d t}=frac{1}{2 sqrt{2^{cos e^{-1} t}}}^{2} operatorname{cosec}^{-1} t log _{e^{2}}left(frac{-1}{|x| sqrt{x^{2}-1}}right) ) ( frac{d y}{d t}=frac{1}{2 sqrt{2^{sec t}}} 2^{sec ^{-1} t} log _{e^{2}}left(frac{1}{|x| sqrt{x^{2}-1}}right) ) So; clearly ( frac{d y}{d x}=frac{d y / d t}{d x / d t} ) ( frac{d y}{d x}=-frac{sqrt{2^{sec ^{1} t}}}{2^{sec ^{-1} t}} times frac{2^{operatorname{cosec}^{-1} t}}{sqrt{2^{cos e c^{prime} t}}} ) ( =-frac{sqrt{2^{cos e^{-1} t}}}{sqrt{2^{sec ^{-1} t}}} ) ( frac{d y}{d x}=-frac{x}{y} )
