True, although not quite following the instruction. (But definitely not as blatant as some other submissions!)

Test	Status	Code Input and Output
1	Pass	x = 0; y_correct = 0; assert(abs(SIN(x)-y_correct)<0.01)
2	Pass	x = pi/2; y_correct = 1; assert(abs(SIN(x)-y_correct)<0.01)
3	Pass	x = pi; y_correct = 0; assert(abs(SIN(x)-y_correct)<0.01)
4	Pass	x = 1.5*pi; y_correct = -1; assert(abs(SIN(x)-y_correct)<0.01)
