WebbFor many, the first expression is simpler than the second since the involved trigonometric functions are eveluated on x, not pi/6-x. But i agree that something might be missing to express what kind of modification the user expect from Sage. However, Sage somehow knows that the two expressions are equal: sage: bool( (sqrt(3)/3*cos(x)+1/3*sin(x ... WebbSin3x. Sin3x gives the value of the sine trigonometric function for triple angle. On the other hand, sin^3x is the whole cube of the sine function. Sin3x is a triple angle identity in trigonometry. The expansion of sin3x formula can be derived using the angle addition identity of the sine function and it involves the term sin^3x (sin cube x).
