WebSolution: Given that, sinB = 3sin(2A+ B) ⇒ sin (2A+B)sin B = 13 ⇒ sinB−sin(2A+B)sinB+sin(2A+B) = 3−13+1 (use componendo-dividendo formula) ⇒ −2cos (A+B).sin(A)2sin (A+B).cos(A) = 24 ⇒ tan(A+B).cot A= −2 ⇒ tan (A+B)= −2tanA ⇒ 2tanA+tan(A+ B) = 0 Webcos2A+sin2A−1 cos2A−sin2A+1 =tan A. Solution Here, you should first look to simplify the numerator and denominator by using the identities for cos 2A and sin 2A. In the numerator, re-writing cos2A as 1−2sin 2A will help cancel the –1 on the end; whilecos2A =2cos 2A−1will be useful in the denominator. tiobrave https://state48photocinema.com
