If `theta+phi=(pi)/(3)` where `theta` and `phi` are positive angles, then the maximum value of `tan theta tan phi` is equal to

If tan theta=3tan phi, then the maximum value of tan^(2)(theta-phi) is

7.If tan theta=n tan phi, then maximum value of tan^(2)(theta-phi) is equal to

If sin(theta+phi)=n sin(theta-phi), then the value of (tan theta)/(tan phi) is equal to

If theta+phi=(pi)/(2) where theta and phi are positive then (sin theta+sin phi)sin((pi)/(4)) is always less than

If cos theta = 3/5 and cos phi =4/5, where theta and phi are positive acute angles, then cos ""(theta - phi)/(2)=

If costheta=(3)/(5)andcosphi=(4)/(5) , where theta and phi are positive acute angles, then cos((theta-phi)/(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

theta+phi=(pi)/(4) then (1+tan theta)(1+tan phi) is equal to

If theta+phi=(pi)/(4),then(1+tan theta)(1+tan phi) is equal to
