if `phi=tan^-1((xsqrt3)/(2k-x))` and `theta=tan^-1((2x-k)/(ksqrt3))` then one of the value of `phi-theta` is

if phi=tan^(-1)((x sqrt(3))/(2k-x)) and theta=tan^(-1)((2x-k)/(k sqrt(3))) then one of the value of phi-theta is

If phi= tan^(-1)(( xsqrt3)/(2k-x)) and psi = tan^(-1) ((2x-k)/(k*sqrt3)) then one value of phi - psi is

If A="tan"^(-1)((xsqrt3)/(2K-x)) and B="tan"^(-1)((2x-K)/(Ksqrt3)) , then the value of A-B is

If 2sec 2theta=tan phi+cotphi , then one of the values of theta+phi is

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

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

If cos theta=(2cos phi-1)/(2-cos phi), then find the value of tan((theta)/(2))
