Question

सिद्ध कीजिए।

cotθ + tanθ = cosecθ secθ 

Sum

Solution

बायाँ पक्ष = cotθ + tanθ

= `costheta/sintheta + sintheta/costheta` .................`[∵ cotθ = costheta/sintheta, tantheta= sintheta/costheta]`

= `(cos^2theta + sin^2theta)/(sintheta xx costheta)`

= `1/(sintheta xx costheta)` ..................`(sin^2theta + cos^2theta = 1)`

= `1/sintheta xx 1/costheta`

= `cosectheta xx sectheta` ..............`[∵ 1/sintheta = cosectheta, 1/costheta = sectheta]`

= दायाँ पक्ष

बायाँ पक्ष = दायाँ पक्ष

cotθ + tanθ = cosecθ secθ.
