Question:Combining functions,

Hi, I want to build recursively defined, piecewise functions.

I first defined my zero-order functions

N40(xi)=piecewise(0<xi and xi<=1);

N50(xi)=piecewise(1<xi and xi<=2);

and I can plot them with desired result

but, how do I combine them, to make first order functions?

 for instance, I want to have a function matematichally defined by:

N41 = (xi-1)*N40 + (2-xi)*N51
