Week Two: Coordinate Geometry of Straight line

**INTRODUCTION:**

Straight lines in coordinate geometry are the same idea as in regular geometry, except that they are drawn on a coordinate plane and we can do more with them. Consider the line in Fig 1. How would I define that particular line? What information could I give you over the phone so that you could draw the exact same line at your end? To learn more, click **here**.

Week Three: Coordinate Geometry of Straight line Cont’d

**INTRODUCTION:**

To determine the distance between two coordinate points, a formula used. said formula is an algebraic expression which can be seen thus- (x_{1}, y_{1}) and (x_{2}, y_{2}).

D=(x2−x1)2+(y2−y1)2 √D=(x2−x1)2+(y2−y1)2

**Example**

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

Week Four and Five: Differentiation of Algebraic Functions

**INTRODUCTION:**

An algebraic function is a function that can be written using a finite number of the basic operations of arithmetic (i.e., addition, multiplication, and exponentiation). In order to take the derivative of these functions, we will need the power rule. To learn more, click **here**.

Week Six: Integration and Evaluation

**INTRODUCTION:**

In mathematics, an **algebraic function** is a function that can be defined as the root of a polynomial equation. Quite often algebraic functions can be expressed using a finite number of terms, involving only the algebraic operations addition, subtraction, multiplication, division, and raising to a fractional power.
