Pentagonal number theorem

Web13. máj 2009 · Call the lengths of the sides a b and c, then add the area of the rectangle to that of the triangle, and maximise. I think there is a problem. Cause we are dealing with three variables but we have just two equtions 1) 2a + 2b + c =P and 2) The one which tells about the total area. By normal convention we diff equation number 2. WebThe pentagonal number theorem occurs as a special case of the Jacobi triple product. Q-seriesgeneralize Euler's function, which is closely related to the Dedekind eta function, and occurs in the study of modular forms.
