Tools at high risk
-
evaluate_pipelineExecuteExecute a sequence of mathematical operations where $LAST in an expression is replaced by the previous result. Currently supports op
-
fourier_transformExecuteNumerical approximation of the Fourier transform F(ω) = ∫ f(t)·e^(-iωt) dt. Provide expression in t and frequency ω. Returns a complex number string. Example: fourier_transform(
-
find_rootExecuteFind root of f(x)=0 using Newton-Raphson method. Provide the expression, variable, and initial guess. Converges quickly for well-behaved functions. Examples: find_root(
-
riemann_sumExecuteNumerical definite integration using Riemann sums. Methods: left, right, midpoint (default), trapezoid. Returns a number. Use when symbolic integral cannot solve the expression....
