प्रश्न
`1+((tan^2 theta) cot theta)/(cosec^2 theta) = tan theta`
उत्तर
LHS = `((1+ tan^2 theta) cot theta)/ (cosec^2 theta) `
=` (sec^2 theta cot theta)/(cosec^2 theta )`
=`(1/cos^2thetaxxcos theta/sin theta)/(1/sin^2 theta)`
=`1/(cos theta sin theta) xx sin^2 theta`
=`sintheta/costheta`
=` tan theta`
=RHS
Hence, LHS = RHS
