Approximation Methods,Calculus,Curves, derivatives,Real AnalysisThe derivative of a differentiable real function f at a can be approximated by the symmetric difference quotient, (f(a+d)-f(a-d))/(2d), where d is small. Reduce the difference d to reduce the error. The symmetric difference quotient is generally a more accurate approximation than the "standard" one-sided difference quotient (f(a+h)-f(a))/hComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemática
