[Lyric] Rates Of Change (Calvin)

Ooo there is an old strategy,
A strategy we all can use,
We start by getting x and y to calculate the rate of change.

If x independent and y is dependent then rate of change would equal delta y over x.

With all this information,
We now all can find,
Average velocity,
Given x and y.

Instantaneous velocity,
Is a big word,
It is the velocity at a certain time.

This velocity,
At this certain time,
Is a tangent to the function,
Any function will do.

You take the givеn time,
Take the givеn equation,
Start by plugging in the time into the equation.
Then you do the same thing,
But with time plus H,
Given these values,
You can now solve V.

To solve for velocity,
You must use the formula,
The formula with the limit as H approaches zero.

With all this information,
You now all can find,
Instantaneous velocity,
Given time and function.

But the real question is,
When is all this used,
Well velocity is used to find,
distance, time, and speed.

What velocity,
Is that car moving at?

What is a balls speed?
At this certain time?
And when does this ball?
Hit this certain ground?
