Question

`5/(sin^2theta) - 5cot^2theta` ची किंमत काढण्यासाठी खालील कृती पूर्ण करा.

कृती: `5/(sin^2theta) - 5cot^2theta`

= `square (1/(sin^2theta) - cot^2theta)`

= `5(square - cot^2theta)   ......[1/(sin^2theta) = square]`

= 5(1)

= `square` 

Answer 1

`5/(sin^2theta) - 5cot^2theta` = `underline(5) (1/(sin^2theta) - cot^2theta)`

= `5(underline("cosec"^2theta) - cot^2theta)   ......[1/(sin^2theta) = underline("cosec"^2theta)]`

= 5(1)

= 5
