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

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

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:

If theta - phi=pi/4 , prove that : (1 + tan theta)(1+tan phi)=2 tan theta .

If theta - phi=pi/4 , prove that : (1 + tan theta)(1-tan phi)=2 .

If tantheta=1/2 and tanphi=1/3 , then tan(2theta+phi) is equal to

If theta=60^@ ,then (frac(1+tan^2theta)(2tantheta)) is equal to…….

If tan theta = (1)/(2) and tan phi = (1)/(3) , then tan(2 theta + phi) is equal to

If sec theta =x+1/(4x) , then tantheta + sec theta is equal to
