Webba/sin (A) = b/sin (B) = c/sin (C) (Law of Sines) c ^2 = a ^2 + b ^2 - 2ab cos (C) b ^2 = a ^2 + c ^2 - 2ac cos (B) a ^2 = b ^2 + c ^2 - 2bc cos (A) (Law of Cosines) (a - b)/ (a + b) = tan [ (A … Step 1: We know that sin a sin b = (1/2) [cos (a - b) - cos (a + b)]. Identify a and b in the given expression. Here a = x, b = 7x. Using the above formula, we will proceed to the second step. Step 2: Substitute the values of a and b in the formula. sin x sin 7x = (1/2) [cos (x - 7x) - cos (x + 7x)] ⇒ sin x sin 7x = (1/2) [cos (-6x) - … Visa mer Sina Sinb is an important formula in trigonometry that is used to simplify various problems in trigonometry. The sin a sin b formula is sin a sin b = (1/2)[cos(a - b) - … Visa mer We know that sina sinb= (1/2)[cos(a - b) - cos(a + b)] ⇒ 2 sin a sin b = cos(a - b) - cos(a + b). Hence the formula of 2 sin a sin b is cos(a - b) - cos(a + b). Visa mer The trigonometric identities which are used to derive the sina sinb formula are: 1. cos (a + b) = cos a cos b - sin a sin b 2. cos (a - b) = cos a cos b + sin a sin b … Visa mer The sina sinb expansion formula in trigonometryfor angles a and b is given as, sin a sin b = (1/2)[cos(a - b) - cos(a + b)]. Here, a and b are angles, and (a + b) and (a - … Visa mer
