About Class 9 Maths Chapter 4 Linear Equations in Two Variables In this chapter, you will get to learn about linear equations and their applications in real life problems.
A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation.
Results are obtained for integral equations on the half line, and for corresponding finite-section equations. Convergence, in the sense of uniform convergence on every finite interval, is proved under ...
