Change angles A and B by pressing "+" and "-" buttons.
The lengths of three arrows appear by checking "Character" box.
You will understand the green arrow is the sum of the red arrow and the blue arrow. That indicates the formula for sin(A+B).
These are the sum and difference formulas:
sin(A+B)=sin A cos B + cos A sin B
sin(A-B)=sin A cos B - cos A sin B
cos(A+B)=cos A cos B - sin A sin B
cos(A-B)=cos A cos B + sin A sin B
