- 1Equation of a Line (parallel)Parallel lines have the same gradient.
y-y1 =m(x-x1)
OR- Substitute the gradient and co-ordinates into the equation to find the y-intercept. - 2Equation of a line (perpendicular)The gradients are the negative reciprocal of the other line.
m1 * m2 = -1
Substitute the gradient and co-ordinates into the equation to find the y-intercept if you need to. - 3Graph of 1/xPlot a table of points. This will help to draw it.
Never reaches (0,0).
Draw the graph according to your points.
Also known as a reciprocal graph. - 4Exponential GraphsPlot a table of points. This will help to draw it.
e.g. y=3^x is an exponential graph.
Draw the graph according to your points. - 5Velocity Time GraphsGradient of the line = acceleration
The total area of the graph = total distance
If you don't know the equation of a trapezium (area), split into triangles and squares to find the area.
If curved - draw a tangent and find the gradient of it. Also, split the graph into triangles and rectangles to find the area. - 6Inequality Graphs and regionsDraw the line as if it was a y=mx+c line.
If it is greater than or equal to, or less than or equal to - draw it with a solid line.
If it is > or < - draw it with a dotted line e.g. - - - - -
Shade the region that is instructed - e.g. 2 and lower would be x<2 - 7Circle equationscentre=origin
radius = x^2 + y^2 = r^2
sqrt r^2 - 8Trigonometry Graphs (sine)sin (x) = 0° = 0
90° = 1
180° = 0
270° = 1
360° = 0 etc. - 9Trigonometry Graphs (cosine)cos (x) = 0° = 1
90° = 0
180° = -1
270° = 0
360° = 1 etc. - 10Triganomic graphs (tan)Tan (x) = 0° = 0
90° = N/A
180° = 0
270° = N/A
360° = 0 - 11—
