I have a Doctorate degree in Mathematics. Maths is a wonderful subject, which one needs in all spheres. It is the basic of all subjects. A few applications are defined below: Trigonometry: Calculus is related with trigonometry and algebra. The fundamental trigonometric functions like sine and cosine are used to define the sound and light waves.Trigonometry is further used in oceanography to measure the heights of waves and tides in oceans. It is used in satellite systems, and to create maps. The famous Pythagoras' Theorem finds its' application in determining how tall a ladder needs to be in order to safely place the base away from the wall so it does not turn over. Probability and Statistics: Probability problems infer conclusions about characteristics of hypothetical data taken from the population. Probability explains the mathematical chance that something might happen, and is used in numerous day- to-day applications. Calculus : We can find the (or global) minimum and maximum values of a function as well as the relative (or local) minimum and maximum values of a function. Differential Equation: Differential equations are applied to predict the world around us, and used in a wide variety of disciplines, from biology, economics, physics, chemistry and engineering. It has applications in exponential growth and decay model, Newton's law of cooling, and Circuit theory, e.t.c. I have teaching experience for more than 15 years. My students are from all corners of the globe, and of all ages. I also make them learn Mathematics in English, so that they can excel in future. I am well acquainted will all the topics of mathematics, at all levels from schools to colleges. Children like my style of teaching.
