Question

sec2θ + cosec2θ = sec2θ × cosec2θ हे सिद्ध करा.

Sum

Solution

डावी बाजू = sec2θ + cosec2θ

= `1/(cos^2theta) + 1/(sin^2theta)`

= `(sin^2theta + cos^2theta)/(cos^2theta*sin^2theta)`

= `1/(cos^2theta*sin^2theta)`   ......[∵ sin2θ + cos2θ = 1]

= `1/(cos^2theta) xx 1/(sin^2theta)`

= sec2θ × cosec2θ

= उजवी बाजू

∴ sec2θ + cosec2θ = sec2θ × cosec2θ
