FindMaximum[f,x] searches for a local maximum in f, starting from an automatically selected point.

FindMaximum[f,{x,x0}] searches for a local maximum in f, starting from the point x=x0. 

FindMaximum[f,{{x,x0},{y,y0},…}] searches for a local maximum in a function of several variables. 

FindMaximum[{f,cons},{{x,x0},{y,y0},…}] searches for a local maximum subject to the constraints cons.

FindMaximum[{f,cons},{x,y,…}] starts from a point within the region defined by the constraints.
