Trigonometry in all triangles The sine rule and cosine rule can be used with any triangle, including right-angled triangles. You should know how to use the sine rule and the cosine rule. You should know when to apply the sine rule and when to apply the cosine rule. Sine rule a/sinA = b/sinB = c/sinC […]
Trigonometry and Right-angled Triangles You should know how to use the trigonometric ratios (sine, cosine and tangent) in order to solve problems with right-angled triangles. Hypotenuse – the longest side of a right-angled triangle, it is always the side opposite the right-angle Opposite – the side opposite the known angle or the angle […]
Circle Properties The Basics Circumference – the perimeter of a circle Diameter – the distance across a circle, passing through the centre Radius – the distance from the centre of a circle to the circumference, plural of radius is radii Tangent – a straight that touches the circumference of the circle at a single […]
Graphs and Curve Sketching You need to be able to plot straight line graphs and sketch curves for quadratic, cubic and trigonometric graphs. You need to understand the effects of transformations of graphs. You need to be able to use graphs to find graphical solutions to equations. Transformations of Graphs Transformations such as translations and […]
