>>11093893Calc 1 is learning (and proving, if instructor is good) those basic differentiation rules, and also learning the basics of anti differentiation. In calc 1 you learn about Reimann sums.
In calc 2 you basically just solve tricky integrals for half the time. The other half is stuff like finding volume and surface area of shapes of revolution, arc lengrh, parametric functions. In calc 2 you also cover infinite series.
Calc 3 is multivariable calculus, vector calculus, and basically an intro to lin alg.
