@ninja_maths just an opinion, but i think it would be best to have a relationship from defining double integrals node to double integrals over rectangulars domains node so students learn first about the approximation of the volume an then learn about different domains
@_MathAcademy_ do you plan to cover more proof based courses as for example topoly or a calculus 1 course but with theorem's demonstrations? Just courious about how you intend to teach that kind of content
@candicandi2357 Si las diapositivas son lo suficientemente buenas y solo les quedan meter detalles que cuentan en clase, piensa en pillarte tablet para poder escribir sobre ellas
