Sine Rule What is the sine rule? The sine rule allows us to find missing side lengths or angles in non-right-angled triangles It states that for any triangle with angles A, B and C Where a is the s...
Pythagoras What is the Pythagorean theorem? Pythagoras’ theorem is a formula that works for right-angled triangles only It states that for any right-angled triangle, the square of the hypotenuse is...
Volume of 3D Shapes What is volume? The volume of a 3D shape is a measure of how much 3D space it takes up A 3D shape is also called a solid You need to be able to calculate the volume of a number ...
3D Coordinate Geometry How does the 3D coordinate system work? In three-dimensional space we can label where any object is using the x-y-z coordinate system In the 3D cartesian system, the x- and y...
Length of an Arc What is an arc? An arc is a part of the circumference of a circle It is easiest to think of it as the crust of a single slice of pizza The length of an arc depends of the size of t...
Radian Measure What are radians? Radians are an alternative to degrees for measuring angles 1 radian is the angle in a sector of radius 1 and arc length 1 A circle with radius 1 is called a unit ci...
Basic Coordinate Geometry What are cartesian coordinates? Cartesian coordinates are basically the x-y coordinate system They allow us to label where things are in a two-dimensional plane In the 2D ...
Linear Piecewise Models What are the parameters of a piecewise linear model? For each linear model there will be The rate of change for that interval mi The value if the independent variable was n...
Logistic Models What are the parameters of logistic models? What can be modelled using a logistic model? A logistic model can be used when the variable initially increases exponentially and then te...
