Inequalities describe ranges of possibilities. This course solves linear inequalities and graphs their solutions as intervals and half-planes.
The course follows the NCERT Class 11 Mathematics chapter Linear Inequalities and has 2 lessons. Each lesson explains the ideas with worked examples and ends with practice questions and full answers. The numbers in every example and question are our own, so the lessons can be used alongside the textbook exercises.
- Linear Inequalities in One Variable, Rules for inequalities, solving and graphing on the number line, systems, and word problems.
- Inequalities in Two Variables and Mixed Practice, Half-planes, graphing systems of inequalities, and a mixed practice set on the chapter.
By the end you will be able to:
- Solve linear inequalities in one variable.
- Represent solutions on the number line.
- Graph inequalities in two variables.
- Solve systems of inequalities graphically.
