- amelius 6y agoYes, I agree that was badly worded, but in any case you need more than those two equations to do anything meaningful with sin(x) and cos(x).
- laszlokorte 6y agobut you could conclude that cos and sin are both jsut the constant function: x->sqrt(0.5)
- filmor 6y agoNot at all, same reason.
