Gradient
Gradient: Gradient is the measure of a line’s steepness (slope). The gradient of a line describes the change in y values as the x value increases by 1. The size of the gradient tells us how steep a line is. … Continue reading

Coordinate Geometry
On a Cartesian plane, the horizontal axis is called the x axis and the vertical axis is called the y axis. The point of intersection of the x and y axes is called the origin. The coordinates of the origin … Continue reading
Linear Equations
There is a Linear relationship between two variables if a uniform change in the independent variable produces a uniform change in the dependent variable. A linear relationship produces a linear graph (straight line). A linear graph is represented by the … Continue reading
Arc, Sector and Circle
Circumference of a circle: C = 2 π r or C = π d where r is the radius and d is the diameter of the circle Arc Length of a Sector: l = Θ/360 × 2 π r … Continue reading
