" 12."tan phi=(40)/(9)

If tan phi=(4)/(3), then the value of tan3 phi, is

If tan theta=(5)/(6) and tan phi=(1)/(11) , then theta+phi =______

phi is an acute angle such that tan phi=(2)/(3) then evaluate ((1+tan phi)/(sin phi+cos phi))*((1-cot phi)/(sec phi+csc phi ))

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

If tan theta=(1)/(2) and tan phi=(1)/(3), then the value of theta+phi is

If tan theta = (1)/(2) and tan phi = (1)/(3) , then the value of theta + phi is

Consider tan theta+sin phi=(3)/(2) and tan^(2)theta+cos^(2)phi=(7)/(4) then find maximum value of (12(theta+phi))/(pi) if (theta+phi)in(0,2 pi)

If tan theta tan phi=sqrt((a-b)/(a+b)) , prove that a-bcos 2theta)(a-b cos 2phi) is independent of theta and phi .

If tan theta tan phi=sqrt((a-b)/(a+b)) , prove that a-bcos 2theta)(a-b cos 2phi) is independent of theta and phi .
