WebThere are some trigonometric identities which satisfy the given additional conditions. Such identities are called conditional trigonometric identities. Example 1 : If A + B + C = π/2, prove that. sin2A + sin2B + sin2C = 4cosAcosBcosC. Solution : sin2A + sin2B + sin2C : = 2sin (A + B)cos (A - B) + sin2C. = 2sin (90 - C)cos (A - B) + 2sinCcosC. sembcorp marine market cap
