Subs f x
WebOne of the most basic operations to be performed on a mathematical expression is substitution. The subs () function in SymPy replaces all occurrences of first parameter with second. >>> from sympy.abc import x,a >>> expr=sin (x)*sin (x)+cos (x)*cos (x) >>> expr The above code snippet gives an output equivalent to the below expression − WebBut now we would like to evaluate this expression for particular 'f(x)' (and possibly multiple times with different expressinos), e. g. for 'f(x) = a*x + b'. It is desirable to have this with something like answer = h.subs({f:a*x + b}) # do not work :( but this substitution do not work inside derivatives...
