• In method solve of class IntegratedCurve, the step of integration needs to be evaluated numerically (using numerical_approx) before calling any algorithm, in order to allow it to be an expression such as pi.
• In method solve, when using Bulirsch-Stoer algorithm ('bsimp'), method ode_solve was called in a wrong way.
• 'Bulirsch' was misspelled in documentation.
• Minor corrections were made regarding rk4_maxima being the default algorithm of method solve.
