Question

If A = 60; B = 30, verify sin (A+B) = sin A cos B + cos A sin B​

Answer 1

Step-by-step explanation:

• A=60;B=30
• sin(A+B)=sin (60+30)=sin 90
• value of sin 90 =1
• 1=

Answer 2

Step-by-step explanation:

A = 60 and B = 30 Now, A + B = 60 + 30 = 90 Also, A – B = 60 – 30 = 30 sin (A + B) = sin 90 = 1 sin A cos B + cos A sin B = sin 60 cos 30 + cos 60 sin 30 Read more on Sarthaks.com - https://www.sarthaks.com/139537/if-a-60-and-b-30-verify-that-sin-a-b-sin-a-cos-b-cos-a-sin-b
