Table of tangents
The table of tangents contains values for every acute angle from 0o to 90o. Each angle has a unique tangent ratio. This ratio is formed when two lines meet to make the angle. Every combination of opposite and adjacent lines that makes a right angled triangle has a unique angle which they make. If we…

Equations of straight lines
The equations of a straight lines describes a relationship between two variables. This variables are usually described as x which is independent variable and y which is dependant variable. The value of x determines the value of y in the line. consider two arbitrary points on a Cartesian plane shown below. Any two points joined…

Equations of straight lines
A straight line is a one-dimensional geometric object that extends infinitely in both directions without curving or bending. It is the shortest path between any two points on the line and has a constant direction. Straight lines passes through some definite points that can be traced on a Cartesian plane. A point on a Cartesian…

Integrating products of secants and tangents
When integrating products of secants and tangents, we are integrating expressions that are in the form: secant and tangent are both trigonometric functions that relate the angles of a right triangle to the ratios of its sides. There are several cases to consider in this type of integration. case 1 This is a case where…

Introduction to HTML 1
HTML stands for Hyper Text Markup Language. It is the standard markup language for documents designed to be displayed in a web browser. It is the language we use to define the content and structure of the web. A markup language is used to format plain text. An HTML document is simply a text file…

How planet earth will end
Will the earth and other planets end or will they live forever? The theory about end of planet earth is as controversial as the information about how it came to existence. From the loud bang theory to creation theory. Nobody seems to give satisfactory answer. Probably it is because nobody was there to witness it,…

Electrical Resistance 1
Electrical resistance is the opposition offered by a conductor to the flow of electric current. It occurs when a charge flowing through a conductor has it’s movement hindered by collisions with the atoms and impurities in the conductor. The collisions scatters the charges leading to the loss of their momentum and energy in the form…

Ohmic and Non-Ohmic conductors
Ohmic conductors are conductors that obeys the ohms law while conducting current. In this conductors, current flowing is directly proportional to voltage across the conductor. Most of metal conductors are Ohmic conductors. In simple terms, for an Ohmic conductor, the relationship between voltage and current is linear. Non-Ohmic Conductors: A non-ohmic conductor, on the other…

Need for a break? That is very much in order
We all need a break from anything that keeps us engaging for a long time. Whether good or bad, everything that takes our and time soon causes us feeling of resentment. We therefore longs for a break from anything that is too much for us. The things that causes us to want a break can…

Resistors: detailed analysis 2
Resistors are materials that offers resistance to the flow of an electric current. Resistors are usually categorized into two: Fixed resistors These are resistor whose resistance is almost constant. Resistors are commonly made from mixture of carbon and carrier material where the two are mixed and baked together. The baked mixture is then covered with…
