If A + B = C, then write the value of tan A tan B tan C.
A+B=C
tan A + tan B = tan C(1- tan A tan B)
tan C – tan A – tan B = tan A tan B tan C.
If α + β - γ = π, and sin2 α + sin2 β – sin2 γ = λ sin α sin β cos γ, then write the value of λ.
If then write the value of
Write the maximum and minimum values of 3 cos x + 4 sin x + 5.
Write the maximum values of 12 sin x – 9 sin2 x.
If 12 sin x – 9 sin2 x attains its maximum value at x = α, then write the value of sin α.
Write the interval in which the values of lie.
If tan (A + B) = p and tan (A – B) = q, then write the value of tan 2B.
If then write the value of tan x tan y.
If then write the value of ab + bc + ca.
If sin α – sin β = a and cos α + cos β = b, then write the value of cos (α + β).
If and then write the value of α + β lying in the interval (0, π/2).
