# Key to IGCSE Mathematics for iPhone

## Publisher's Description

From Sushil Asar:

With over 10 years of teaching experience I have compiled all my teaching methodologies in this app to help math students all over the world. Key to IGCSE mathematics is a crisp revision course for the IGCSE math examination. The app covers 10 chapters.Each chapter has several sub topics with explanation and solved practice problems. Each subtopic has revision notes with an optional audio for detailed explanation. Chapter Index 1. Number- a. Sequences b. nth term of a sequence c. sets - union, intersection and element of a set d. Word problems involving sets. e. Ratio f. Direct proportion g. Inverse proportion and much more 2. Algebra a. Cross multiplication b. Cross multiplication 2 c. Subject of the formula 1 d. Subject of the formula 2a e. Subject of the formula 2b f. Factorising type 1 g. Factorising type 2 and 3 h. Solve using - completing the square and much more 3. Functions a. Functions 1 b. Functions 2 c. Functions 3- Inverse function1 d. Functions 4- Inverse function 2 and much more 4. Indices a. Indices 1 - Rules of Indices b. Indices 2- Exponential equations and much more 5. Scale factor, Area factor, Volume factor a. Definitions b. Example 1a c. Example 1b and much more 6. Mensuration a. Definitions and formulas 1 b. Definitions and formulas 2 c. Example 1 and much more 7. Trigonometry a. Definitions b. Example 1 c. Pythogoras theorem 1 d. Pythogoras theorem 2 e. Angle of elevation and depression definition f. Example 1 - angle g. Example 2 - angle h. Sine Rule i. Example 1- sine rule j. Example 2-sine rule and much more 8. Probability and Statistics a. Definitions of probability b. Problem 1- probability c. Tree diagram d. Example 1 - tree diagram e. Mean, median and mode f. Mean for grouped data and much more 9. Matrices and vectors a. Order of a matrix b. Adding and subtracting matrices c. Multiplying matrices d. Example - multiplying matrices e. Determinant of a matrix f. Inverse of a matrix g. Adding and subtracting vectors and much more 10. Graphs a. Gradient b. Speed, distance, time and acceleration c. Equation of a line and much more How to use this app While revising for your exam go through every chapter and all practice problems within it. Repeat the practice problems in your note book or do two to three problems of similar type from your text book to build your confidence. Finally try to solve past IGCSE math question papers. Math can never be done by just looking at it, you need to practice, practice and practice.
