1)\[\huge{\frac{(\frac{sinx}{cosx})^2}{\frac{1}{cosx}}}\]\[=\frac{\sin^2x}{cosx}\]\[\huge{=\frac{sinx}{cosx}\times sinx}=tanxsinx\]
OpenStudy (lalaly):
same thing for 2 \[\huge{\frac{\cot^2x}{cosecx}}\]\[\huge{=\frac{(\frac{cosx}{sinx})^2}{\frac{1}{sinx}}}\]\[\huge{=\frac{\cos^2x}{sinx}}=\frac{(1-\sin^2x)}{sinx}\]
