[" If "tan theta=(1)/(2)" and "tan varphi=(1)/(3)" then the value "],[" of "theta+varphi" is "]

If tan theta=(1)/(2) andtan varphi =(1)/(3), then the value of theta+varphi is (pi)/(6) (b) pi(c)0(d)(pi)/(4)

Given both theta and phi are acute angles and sin theta=(1)/(2),cos varphi=(1)/(3), then the value of theta+varphi belongs to (a)((pi)/(3),(pi)/(2)]( b) ((pi)/(2),(2 pi)/(3)] (c) ((2 pi)/(3),(5 pi)/(6)] (d) ((5 pi)/(6),pi]

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

If tan theta=(2x-K)/(K sqrt(3)) and tan varphi=(x sqrt(3))/(2K-x), then show that | varphi-theta|=30^(@)

If tan theta = (2x - K)/(K sqrt3) " and " tan varphi = (xsqrt3)/(2 K-x), "then show that" |varphi - theta| = 30^(@).

If tan 2 theta.tan 4 theta =1 , then the value of 3 theta is

If sec theta+tan theta=(1)/(2) The value of tan theta =

If sec theta+tan theta=(1)/(2) The value of tan theta =
