Angles properties
This post about is the the Angle tangent properties. Formulas for the radius of a circle, the diameter of a circle, the circumference (perimeter) of a circle. Therefore It also include the length of chord of a circle. Because of length of chord angles also varies. Similarly other properties also involve. Explore, prove, and apply important properties of circles […]
St. Line Graph
Straight line graphs. The graph of each of equations is a straight line: If an equation can be rearranged into the form y = mx +c, then its graph will be a straight line. ax +by= c can be rearranged as (which can be re-written as y = mx+c). Therefore vertical lines have equations have slope undefined form x =k . Hence graph depend on […]
Binomial Theorem
Binomial theorems is another ways of expansion of two terms. Another way it is generalised form of expansion. Due to expansion of two term it is binomial. “What are the binomial coefficients?” . It shows how to calculate the coefficients in the expansion of (a + b) n. The symbol for a binomial coefficient nCr. As well as pascal […]
Demand and Supply (Rev. notes) IGCSE
Supply and Demand. Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price. Hence it give relation between them. Therefore there graph is St. line. Supply and Demand
