Expanding brackets

This chapter explores expanding brackets. It covers multiplying a bracket by a single term, and multiplying pairs of pairs of different brackets. Rectangle perimeters Below is a rectangle To calculate the perimeter of a rectangle, we add up all of [...]

Algebra

Algebraic Manipulation

This chapter explores algebraic manipulation. It covers expanding brackets with common factors and changing the subject of a formula. Expanding brackets Suppose we wanted to expand and simplify; Here we’re asked to multiply each of the terms in the left [...]

Calculus

Solids of Revolution

When you take a fraction such as y = f(x) or between two limits on the x-axis and rotate this part of the curve around the x-axis the shape formed will be a 3 dimensional shape. In this lesson I [...]

Y=mx+c

In this chapter we’re going to be looking at y=mx+c graphs. We shall explore the effects of m and c on the line in the y=mx+c equation. We shall then explore how to find the equation of a line drawn [...]

Kinematics

Motion in a vertical Plane

This chapter covers motion in a vertical place. It covers applying the constant acceleration formulae to solve problems relating to vertical motion under gravity and the constant acceleration formulae. What is gravity? Gravity is the force that planets exert on [...]

    Lowest common multiple (LCM)

    This chapter covers lowest common multiple. It covers how to find the lowest common multiple (LCM) of two numbers and using the LCM to compare fractions. The lowest common multiple (LCM) of given numbers is the number that appears in [...]

    Shape

    2D shapes and 3D shapes

    In this simple chapter we’re going to look at 2D shapes and 3D shapes. We shall also explore their names and properties. In mathematics especially the area of shape such as trigonometry and scales we use shapes all the time [...]
