Differentiation Calculus is about finding the Derivative at a certain point of a curve. The derivative is the Slope of the line at that curve. More precisely, the slope is the line Tangent to that certain point of the curve.

Slope of the tangent line is calculated by dividing the Rise over the Run at that tangent line. And we can get the values of the rise and the run by using a Secant line of that curve.

Now, let's do some real math! Find the derivative of the following functions and simplify your answers.
1. f(x) = 6
2. g(x) = x^2
3. y = x^2 + x + 8

Decimals are numbers that has one decimal point.  The symbol inside these pair of parentheses (.) is called a decimal point. So, an example of decimals are: 5.0, 2.3, and 1.0001.

The study of decimals is the natural progression in learning the numbers used in Math. Why? Because a decimal is another way to write a fraction. As a matter of fact, the numbers after the decimal point is the fractional part of the number.

Convert the following fractions or expressions into decimals. Be sure to simplify your answer.
1. 1/2
2. 3 + 4/5
3. 67/900
Convert the following decimals or expressions into fractions. Be sure to simplify your answer.
4. 123.45
5. 7.8 + 9.10

Back to basic math!
