If it's too complicated, don't tell me, but... what's 'integration'?

Is that where you substitute algebraic symbols into an equation instead of putting values for those symbols in? (Is it the opposite to 'substitution'?)


Laugh at me if you want... we haven't learnt that yet though...

You'll learn integration in year 12, dw if you haven't learnt it. It's the "opposite" process of differentiation.

Integration falls under a branch of mathematics called Calculus. Calculus is all about investigating rates of change and the behaviour of systems. There are two main sub-branches of calculus. One is called differential calculus which is concerned with finding the gradient (instantaneous rate of change) behaviour of a curve. The other is called integral calculus which is concerned with areas and volumes enclosed by curves as well as investigating the properties of a system (i.e. modelling physical systems).

Other than elementary arthemetic (addition, subtraction etc), calculus is one of the widely used tools in virtually every area of science, even including the social sciences.

so, from what i ve seen here, i gather i can use it straight away in any circumstances including hsc, is that right??
