What is Pythagoras' theorem?
Pythagoras' theorem states that in a right-angled triangle with legs a and b and hypotenuse c, a² + b² = c². The Pythagoras in 2D and 3D notes cover this in full.
What are the circle theorems?
The core circle theorems are: the angle at the centre is twice the angle at the circumference; angles in the same segment are equal; opposite angles in a cyclic quadrilateral sum to 180°; the alternate segment theorem; and the radius results, that a tangent is perpendicular to the radius and the perpendicular from the centre bisects a chord. The Circle Theorems notes cover this in full.
How do you find the volume of a cylinder?
Volume of a cylinder = π × r² × h, because a cylinder is a circular prism. The Area, Perimeter, Surface Area and Volume notes cover this in full.
What is SOH CAH TOA?
SOH-CAH-TOA is the mnemonic for the three trigonometric ratios in a right-angled triangle: sin θ = opposite ÷ hypotenuse, cos θ = adjacent ÷ hypotenuse, and tan θ = opposite ÷ adjacent. The Trigonometry Review notes cover this in full.
How do you find the surface area of a cylinder?
Total surface area of a cylinder = 2πrh + 2πr²: the curved surface plus two circular ends. The Area, Perimeter, Surface Area and Volume notes cover this in full.
What does the graph of y = sin x look like?
The graph of y = sin x is a smooth wave through (0°, 0), peaking at (90°, 1), crossing zero at (180°, 0), troughing at (270°, −1) and returning to (360°, 0). The Sketching Sine, Cosine, and Tangent Graphs notes cover this in full.
What does the graph of y = cos x look like?
The graph of y = cos x is the same wave shape as sine but starts at its peak: (0°, 1), crossing zero at (90°, 0), troughing at (180°, −1), crossing zero at (270°, 0) and peaking at (360°, 1). The Sketching Sine, Cosine, and Tangent Graphs notes cover this in full.
How do you find the area of a trapezium?
Area of a trapezium = ½(a + b)h, where a and b are the parallel sides and h is the perpendicular height. The Area, Perimeter, Surface Area and Volume notes cover this in full.
