B. If you decided to try and verify the student's claim, you'd start with one side of his equation and try to manipulate that side until it looks like the other side. But, that may
turn out to be a lot of unnecessary work if, in fact, the student's claim is false. So,
instead, try something else. Consider a right triangle with angles a and b. Calculate the
values in the chart below, using three (3) various values of a and b.
a
a + b
b
sin(a+b)
sin a
sin b
sin a + sin b
