sin a sin b sin c formula

Howto know which formula to use; The sine rule. The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. {\sin B}} = \frac{c}{{\sin Asbelow ``````````````````````````````````````````````````````````````````````````````````````````````````````````````````` Let us consider two unit vectors in X-Y plane as follows : hata-> inclined with positive direction of X-axis at angles A hat b-> inclined with positive direction of X-axis at angles 90-B, where 90-B>A Angle between these two vectors becomes theta=90-B-A=90-(A+B), hata Step1: Given information. Given that, sin - 1 a + sin - 1 b + sin - 1 c = π. Hence A, B and C can be assumed to be angles of the triangle. = sin A 1 − sin 2 A + sin B 1 − sin 2 B + sin C 1 − sin 2 C = sin A cos A + sin B cos B + sin C cos C ∵ 1 − sin 2 θ = cos θ. Q Prove that tan A + tan B tan A - tan B = sin A + B sin A - B . Q. If tan A = x tan B, prove that sin A - B sin A + B = x - 1 x + 1. Q. Evaluate ∑ sin(A+B)sin(A−B) cos2Acos2B. Q. If A, B, C be the angles of triangle ABC then (sinA+sinB)(sinB+sinC)(sinC+sinA)>sinAsinBsinC. Q. Solvefor b. b = − (a sin(c))2 + c2 + a cos(c) b = − − (a sin(c))2 + c2 + a cos(c), ∣a∣ ≤ ∣ sin(c)∣∣c∣ or ∃n1 ∈ Z : c = π n1. Steps Using the Quadratic Formula. Steps for Completing the Square.
