I love astronomy but I find some of the math impossible to understand. I dont get calculus
Calculus isn't too bad. Derivatives are just rates of change. Everything has a rate of change, even acceleration changes, so you get levels of change. Position's rate of change is velocity, whose rate of change is acceleration, whose rate of change is jerk, and so on.
Oh an integrals are just infinite sums, or sums of infinite cross sections of a volume
Its the syntax of it that makes it so daunting!
