|acceleration||The acceleration of an object measures the rate of change in its velocity. We use the second derivative [ f ''(t)] to calculate this.|
An angle between 0o and 90o.
|addition rule (probability)||
P(A or B) = P(A) + P(B) – P(A and B)
We can use this for all types of events. However, if the events are mutually exclusive, we do not need the “ – P(A and B)” part. This is because P(A and B) = 0 for mutually exclusive events.
When a number is added to its additive inverse the answer is zero.
Two angles are adjacent if they share the same vertex and have one side in common between them.
An expression made up of any number of terms seperated from each other by + an -.
A fraction which contains variables.
When lines are parallel, we have equal alternate angles. Look for a Z or a N.
This is a series in which every term has the opposite sign from the preceding term.
e.g. 1 - 3 + 5 - 4 + 9 . . .
Perpendicular height of a shape. A triangle has three altitudes.
|analitical geometry||This is the branch of mathematics that uses algebra to help in the study of geometry.|
|angle of depression||
Measured from the horizontal downwards.
|angle of elevation||
Measured from the horizontal upwards.
This is the pointed tip of a cone or pyramid.
|arc of a circle||
An arc is part of the circumference of a circle.
The amount of surface or the size of a surface, measured in square units.
Sequences with a constant first difference i.e. you need to add or subtract the same amount to get the next term.
(e.g. 5 ; 1 ; -3 ; -7 ; . . . )
You get this when you add the terms of an arithmetic sequence.
(e.g. 5 + 1 - 3 - 7 - . . .)
|ascending order||From smallest to biggest.|
A straight line which a graph approaches, but never reaches. In the example below, we have a horizontal asymptote.
A mathematical fact that is accepted to be true without needing to prove it.
e.g. a tangent to a circle is perpendicular to a radius of that circle, at the point of contact
|axis of symmetry||
The line which divides a shape (or graph) so that one half is the mirror image of the other half.
