For 10 points, name this number whose sum with itself is two.
As a consequence of Lagrange's theorem, this is the size and number of all proper subgroups of a group of prime order. This is the genus of a torus and the number of points mapped to a given point by a bijection or invertible function, and when using this many variables, there is no need for a (*) partial derivative. Equal to the limit as x approaches zero for sine x over x, it is the maximum value of the sine and cosine functions. Linear equations have this many solutions, and it is used in multiplicative identity, meaning its product with a number is that number itself.
