Visual Proof for sin(A+B) = sinAcosB + cosAsinB

Proof: sin(a+b) = (cos a)(sin b) + (sin a)(cos b)

Proof of sin(A+B)=sinAcosB+cosAsinB

cos(A-B)=cos(A)cos(B)+sin(A)sin(B) proof - geometrical

Trigonometry : Proof of sin (A + B) = sin A cos B + cos A sin B

Proof: cos(a+b) = (cos a)(cos b)-(sin a)(sin b)

sin(A-B)=sin(A)cos(B)-cos(A)sin(B) proof - geometrical
