Derivation of complex abstract functions
The new version of CAS has improved many functions such as this function
Code: (diff(∫(∫(f(sqrt(x^2+y^2)),x,(sqrt(t^2y^2)),sqrt(t^2y^2)),y,t,t),t,3)(t>0)) Code: 2*π*t*diff(f(t),t,2)+4*π*diff(f(t),t) But there are errors in two functions。 Code: ∂(∫(((f(((a^2+a*x)/x)))+f(((a^2+x^4)/x^2)))/x,x,1,a),a) Code: ((f(2*a))+f(a^2+1))/a Code: ∂((f((a^2/x^2)+x^2)(f((a^2/x)+x)))/x,x) Code: (f((a^2+x^2)/x)(f((a^2+x^4)/x^2)))/x^2 study hard, improve every day
