WHAT IS CALCULUS?
What the heck is calculus?
You're totally like…
OMG tell me I NEED TO KNOW!!
Dadadadaduh calculus with Krista
It's kind of an important question, because
it's sort of what you need to know to pass
your class.
RIGHT?!!
Right!
OKAY, so today I'm going to tell you about
what calculus is, what it allows you to do,
and a little bit about who created it.
That way you'll have someone to blame when
you get angry about having to take a calculus
class in the first place!
uggghhhh!
Alright, so who created calculus?
The guys you want to get mad at are Gottfried
Leibniz and Isaac Newton.
But you may want to cut Isaac some slack…
because there's that whole gravity thing (apple
drops from ceiling?)… plus some other stuff
he did… okay so I guess he was pretty cool,
but you can still be mad!
People argue about whether Leibniz was the
first one to discover calculus, or if Newton
first… they're like… it was Liebniz!
And then the other people are like… no it
was Newton… and then they're like, grr…
and then it's like aghhh… but... basically
all you need to know is that they invented
it at the same time.
So what did they discover?
What IS calculus?
Well, in the same way that Geometry is the
study of shape and Trigonometry is the study
of triangles specifically, calculus is the
mathematical study of change.
Calculus has two major branches, differential
calculus, or derivatives, and integral calculus,
or integrals.
Derivatives are all about rates of change,
or slopes of functions.
Integrals, on the other hand, allow you to
find area.
Derivatives and integrals are inverse concepts
of each other which are related to each other
through the Fundamental Theorem of Calculus,
which is really going to make your head spin
when you get to it.
GET READY!
Soooo….
why do you care, again?
You CARE because you really need to know how
fast this function is increasing and decreasing,
and how to find the area under this one!
Don't you?!
Well, maybe you don't.
But if you're going to be a doctor or an engineer
or even an astrophysicist, calculus has a
lot of really cool applications to your field,
so you should give it a chance!
Promise you'll try?
Okay GREAT I'm SO GLAD you said yes!!

When you do you'll get my e-book, integralCALC's
Calculus I Survival Guide, which breaks down
all of CALC I's toughest concepts into language
you can actually understand.
It's a great place to get started, so make
sure you click that link down below!
people argue about whether no no no no.
click the link…no that's thumbs down.
Cuz there's that whole gravity thing, some
other stuff he did, do we have an apple?
That's perfect.
How's my hand, how's my hand looking?
Woop.
Closer, closer, closer.
Sweet.
It was Leibniz, it was blah blah blah.
La da da da, or blah blah.
Ok, that's good.
Perfect, she's fabulous!
