Natural speed please but with small pauses between the different sentences
A series is the sum of the terms of a sequence
A finite sequence is a sequence that comes to an end
An infinite sequence is a sequence that never ends
A recursive formula is a way to define a sequence using the previous terms
The explicit formula is a formula that can give you any term of the sequence
A geometric sequence is a sequence in which each term is obtained by multiplying the previous term by a specific number.
An arithmetic sequence is a sequence in which each term is obtained by adding a specific number to the previous one
The common ration is the ratio between two consecutive terms in a geometric sequence
The common difference is the difference between two consecutive terms in an arithmetic sequence
A geometric sequence is a sequence in which the ratio between any two consecutive terms is constant
An arithmetic sequence is a sequence in which the difference between any two consecutive terms is constant
An event is a set of possible outcomes
An outcome is a possible result of an experiment
The sample space is the set of all possible outcomes
Mutually exclusive events are events that cannot both occur at the same time
The complement of A is the event that contains all the outcomes that are not in an event A
Events that are exhaustive and mutually exclusive form a partition
Equally likely events are events with equal probabilities
The vertex form of a quadratic function is given by f(x)=a(x-alpha)2+beta
The factored form of a quadratic function is given by f(x)=a(x-x_1)(x-x_2)
The standard form of a quadratic function is given by f(x)=ax2+bx+c
If a is negative, the parabola opens down
If a is positive, the parabola opens up
The x-value of the vertex is -b/2a
