Find the general solutions of the following equation: `sintheta=tantheta`

Explanation

Given`,sintheta=tantheta`

=`sintheta=(sintheta)/(costheta)​`

=`sinthetacostheta=sintheta`

=`sinthetacostheta−sintheta=0`

=`sintheta(costheta−1)=0`

either `sintheta=0 `or `costheta−1=0`

either` sintheta=0 `or `costheta=1`

or` sintheta=0` or `costheta=cos0 `
