admin In the previous lesson, you learned about functions and different ways to represent a function. One of the way to represent the function is using graphs. In this lesson, you will explore the graphs of functions and understand how to determine the domain and range of function from its graph. You will learn about vertical … Read more
In the previous lesson, you learned about Cartesian coordinate system, graph of equations and linear equations. These are prerequisites to learn about function in this lesson. A function is a relation between two sets – set A and set B, where each element of set A is related to exactly one element of set B. … Read more
Linear equations form the basis for linear algebra. In the previous lesson, you learned about graph of equations plotted using points on a Cartesian plane, intercepts and symmetry of graphs. You will learn about a graph of linear equations of two variables in this lesson. The graph of linear equation is a straight line The … Read more
In the previous lesson, you learned about graph of equations which is points on a Cartesian plane. The graph of equation has some other interesting characteristics. You will learn about two such properties in this lesson – Intercepts and Symmetry of Graph. Intercepts The intercepts are the points where graph touches the x-axis or y-axis. … Read more
In the previous lesson, you learned about co-ordinate system. You know than a point is plotted on Cartesian plane with x-axis and y-axis. A point has two values – and . For example, is a point. Graph of Linear Equations Therefore, expressions involving two variable can also be plotted using the Cartesian plane known as … Read more
Cartesian plane is a two dimensional co-ordinate system. This system has two axis – the x-axis and the y-axis. The center of the Cartesian plane is called the origin. The x-axis and the y-axis divide the plane into 4 different quadrants as shown in the figure above. The axis are real number line with 0 … Read more
In the previous lesson, you learned about hardware part of a system. If you leave I/O then only CPU and memory is left in the system. In this lesson, you learn the relationship of CPU (Processor) with memory by understanding activities of a CPU. The main function of CPU is to execute a program which … Read more
In the previous lesson, you were introduced to the computer organization. You learned about system hardware and main components that make a computer system and software layer to help a user interact with the computer system. In this article, you will learn about the hardware part of the system in more detail. The system hardware … Read more
In this article, you will begin learning Computer Organization. You appreciate the complexity involved in building a basic computer and type of specialize components required to make a computer. The entire computing machine comes down to two important thing – Processor (or CPU) and Memory. A computer cannot function without these minimum components. The purpose … Read more
In previous lessons, you learned about graph models and some basic graph terminologies. In this lesson, you will learn about simple graph types, we learned earlier that a simple graph is one in which each edge has two unique vertices. Simple Graph Types The following is a list of simple graph types that we are … Read more
