Establish sum and difference identity sin(a + b) + sin(a - b) = 2sin a cos b
Visual Proof for sin(A+B) = sinAcosB + cosAsinB
sina+sinb=2sin(a+b)/2cos(a-b)/2 三角恒等式 (ヒンディー語) であることを証明します。
三角法 : sin の証明 (A + B) = sin A cos B + cos A sin B
sin(A+B)+sin(A-B)=2sin(A)cos(B)
証明: sin(a+b) = (cos a)(sin b) + (sin a)(cos b)
