Derivative and differential, definite integral and indefinite integral, calculus of many sum functions and ordinary differential equations all belong to the category of calculus, while high numbers also include functions and limits, spatial analytic geometry, infinite series, etc., all of which intersect calculus to some extent. For example, L'H?pital's law in limit requires derivation, the solution of normal and tangent in spatial analytic geometry requires derivation, and the summation function of infinite series also requires calculus.
Some colleges and universities study advanced mathematics and some calculus, but the contents are basically the same.
