Hi, I think there is an error when `lambdifying` the sinc function, at least using 'numpy'. Sympy defines the sinc function as unnormalized; i.e sin(x)/x, while numpy defines it as normalized sin(pi.x)/(pi.x). So, the evaluation for [-1, 0, 1] is not the same: >>> import sympy as sp >>> f =

Re: [sympy] GSoC 2016: Singularity Functions

I agree. One should start directly from the loading function q(x). The general steps are: 1. Start with the loading function q(x) 2. Integrate to get the shear function V(x). 3. Integrate again to get the bending moment function M(x). 4. Integrate to get the slope function E*I*v’(x). 5.
