If `sintheta=1/2, cosphi=1/3` then `theta+phi` belongs to, where `0

If sin theta=(1)/(2)cos phi=(1)/(3) then theta+phi belogs to where 0

If sintheta=1//2,cosphi=12//13, where theta lies in the second quadrant and phi in the fourth then : tan(theta-phi)=....

If sintheta=3/5,tanphi=1/2 and pi/2ltthetaltpi phi

If sintheta=3/5,tanphi=1/2 and pi/2ltthetaltpi phi

Given both theta and phi are acute angles and sin theta = (1)/(2), cos phi = (1)/(3) , then the value of theta + phi belongs to

Statement:1 if cos theta=1/7 and cos phi = 13/14 where theta and phi both are acute angles, then the value of theta-phi is pi/3 . Statement:2 cos(pi/3)=1/2

Statement:1 if cos theta=1/7 and cos phi = 13/14 where theta and phi both are acute angles, then the value of theta-phi is pi/3 . Statement:2 cos(pi/3)=1/2

If theta and phi are acute angles, sin theta=1/2, cos phi= 1/3 , then the value of (theta + phi) is:

If sintheta=5sin(theta+phi) then tan(theta+phi)=
