If `sin theta =1/2` `cos phi =1/3` then `theta+phi` belogs to where `0 lt theta , phi lt pi/2`

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

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

If sin theta = cos phi , then the possible values of (1)/(pi) (theta pm phi - (pi)/(2)) are

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 sin theta sin phi - cos theta cos phi+1 =0 then the value of 1+ cot theta tan phi is-

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

If 3(cos 2phi-cos2theta)=1-cos2phi cos2theta , then tan theta= k tan phi , where theta, phiin (0,(pi)/(2)) , where k =
