Jika A+B = 30○ dan sin A cos B = 1/3 maka sin A-B =......
Galladeaviero
Sin(A+B) = sin A cos B + cos A sin B sin 30°= 1/3 + cos A sion B 1/2 = 1/3 + cos A sinB cos A sin B = 1/2 - 1/3 = 1/6 . sin(A-B) = sin A cos B - cos A sin B sin (A-B) = 1/3 - 1/6 = 1/6 .
sin 30°= 1/3 + cos A sion B
1/2 = 1/3 + cos A sinB
cos A sin B = 1/2 - 1/3 = 1/6
.
sin(A-B) = sin A cos B - cos A sin B
sin (A-B) = 1/3 - 1/6 = 1/6
