How To: Derive the area of a circle

This video is about deriving the area of a circle of radius 'r' using polar co-ordinate. First, we draw a circle and its radius 'r'. Then draw another radius close to it, so that it forms a small triangle-like figure. To find the area of the complete circle, divide the circle into similar small triangles. The area of each triangle is given by half the product of its perpendicular and the base. We give the angle between the two radii as d?. We get the area of the small triangle by substituting...

How To: Properly read a decimal number

Decimal numbers are numbers which contain a integral part before a point and a decimal part after the point. The first step in solving decimal arithmetic is being able to understand decimal numbers. Reading a decimal number is similar to reading a whole number except for a few minor differences. In a normal number the right most digit is ones place and the place next to it is tens place and so on the value of the position increases as you move left. But a decimal number starts from a tenths p...

How To: Use functioning & static dominant chords in jazz guitar

In this video, we learn how to play Jazz guitar: Functioning & Static Dominant Chords. When you play an A7 going to a D chord, you are playing a functioning dominant, because a five chord always wants to go to a one chord. This is because of the tension in the five chord and how it resolves to the one chord. You will hear that the chord wants to go to a different chord, so make sure you understand this concept as you are playing. If the chord does go to the other, it's referred to as a functi...

How To: Work with exponential growth functions in mathematics

Exponential functions are functions which contains terms which are integers raised to the power of variables. Note that the variables are not raised to the power of integers, but the integers are raised to the power of variables. Variables raised to the power of integers are called as polynomials and are a different class of functions. But exponential functions grow very fast than polynomials with the increase in the value of the variable. To understand the growth of these functions take a si...

How To: Sketch the graph of a piecewise function

This video teaches us to draw the graph of a piecewise function. This is shown using two examples. In the first example we have 'y' equal to 'x + 2' for x less than zero and '1 - x' for x greater than equal to zero. We plot two points on the function for x less than zero and do the same for the function with x greater than equal to zero. The graph for the first function is erased for x greater than equal to zero, and the same is done for the second function for x less than zero. Note that the...
