  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \sin \: θ =  \frac{1}{ \cosec θ}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \sin θ =  \frac{perpendicular}{hypotenuse} ----- 1

 \:  \:  \:  \:  \:  \:  \: cosec  \: θ =  \frac{hypotenuse}{perpendicular} -----2

multiply \: equation {}^{1}   \: with \: equation {}^{2}

 \:\:\:\:\sin \: θ \:   \times \cosec \:  θ =  \frac{p}{h}  \times  \frac{h}{p}

 \:\:\:\:\sin \: θ \:   \times \cosec \:  θ  = 1

\:\:\:\:\sin \: θ \:    =  \frac{1}{ \cosec \:  θ}
