can many one functions be invertible?
We know that, any function could be invertible when it is only satisfies on and only condition, and that is the "Bijection Property" of that perticular function. So let's talk about the Trigonometrical functions; such that Sine, Cosine and Tangent and we know that these are many one functions by the property of "periodicity of function".These functions takes the same value at many points;instead of this reason how can the Inverse of each "Trigonometrical Functions" can exists...?
Specially this video reveals the reason behind our problem.
