Symbolic coverage: polynomials, 1/x, eˣ, aˣ, sin, cos, tan, sec, csc, sinh, cosh, √x, ln x, linear substitutions like f(ax+b), and integration by parts for xⁿ·eᵃˣ, xⁿ·sin(ax), xⁿ·cos(ax) and xⁿ·ln x. When no symbolic form is found, a definite integral is still computed numerically using adaptive Simpson.
