not much

LIAR. we do it in maths so ner ner ner ner ner.

Up until calculus, you can essentially deal with functions of a

constant slope (a straight line). I.e.: y = 1/3x + 9. We know the

slope on that function is 1/3. However what is the slope of y =

e5x+sin(9x)? It's y' = 5e5x+9cos(x)

You should also know trigonometry and can use some trig

functions to deviate from constant slopes, but you really don't

know how to find the slopes. What is the slope of y = cos(9x)? It's

y' = -9sin(9x)


Calculus teaches you two fundamental operations (and a whole lot

of application with these two operations):


1) How to find the slope of a curve (the derivative)

This let's you find the maximum and minimum's of a function,

optimize problems (i.e., figure out how to use the least amount of

materials given some parameters), and has and endless amounts of

utility.


and


2) How to find the area under a curve. (the integral)

This let's you find the totals for a number of problems

(example, find the total accumulated amount of money, given a

function that relates time and money), let's you calculate the real

areas, volumes, etc. of realistic surfaces (not everything is

shaped like a box or triangle), and also has endless amounts of

utility.



If you want to go into any science, engineering, research field,

or just any technical field, you are going to want to have

calculus. It is a fundamental subject, that teaches you operations

(must like addition and subtraction), finding thedeterminateand

integrals are too operations.
