WebA square number is a number multiplied by itself. This can also be called 'a number squared'. The symbol for squared is ². 2² = 2 x 2 = 4 3² = 3 x 3 = 9 4² = 4 x 4 = 16 5² = 5 x 5 = 25 The square... WebFactors are numbers that divide exactly into another number. For example, the factors of 8 are: 1, 2, 4, 8 Factors can be shown in pairs. Each pair multiplies to make 8. The factor pairs of 8 can...

WebEquation of a circle. The general equation of a circle normally appears in the form \({x^2} + {y^2} + 2gx + 2fy + c = 0\). where \(( - g, - f)\) is the centre of the circle . and \(\sqrt {{g^2} + {f^2} - c}\) is the radius.. Notice that for the circle to exist, \({g^2} + {f^2} - c\textgreater0\). Look at the following worked examples. WebIf we think of a simple function such as multiply by 3, we can determine a set of output values. Instead of writing Function = multiply by 3 we can use algebra.

WebExample 1. We can calculate the gradient of the line above by selecting two coordinate points that the straight line passes through. \ [m = \frac { { {y_2} - {y_1}}} { { {x_2} - {x_1}}} = \frac {5-2} {2-1}=\frac {3} {1}=3\] Now that we know the gradient, we can calculate the angle that the straight line makes with the positive direction of the ...
