The smallest value of theta satisfying t...

The smallest value of `theta` satisfying the equation `sqrt(3)(cottheta+t a ntheta)=4` is `2pi//3` b. `pi//3` c. `pi//6` d. `pi//12`

Text Solution

Verified by Experts

Given,`sqrt(3)(cottheta+t a ntheta)=4`
=`(cottheta+t a ntheta)=4/sqrt(3)`
=`costheta/sintheta+sintheta/costheta=4/sqrt(3)`
=`1/(sinthetacostheta)=4/sqrt(3)`
=`sqrt(3)(sinthetacostheta)=4`
=`sqrt(3)/2=sin2theta`
=`sin 60=sin2theta`
