Unit 3: Trigonometry/ Sequences and Series
In order for your child to be successful, it is important to be consistent with the mathematical vocabulary and
processes that will be implemented this year in Algebra 2. You may find this resource helpful when
supporting your child at home.
Unit Concepts
Concept
Explanation
Sequence
An ordered list of numbers; the
numbers in this ordered list are
called "elements" or "terms".
Series
The value you get when you add
up all the terms of a sequence;
this value is called the "sum".
Arithmetic
Sequence
Geometric
Sequence
Recursive Rule
Examples
An arithmetic sequence goes
from one term to the next by
always adding (or subtracting)
the same value.
A geometric sequence goes
from one term to the next by
always multiplying (or dividing)
by the same value.
A recursive rule gives you the
beginning term or terms of a
sequences and then tells how an
is related to one or more
preceding terms.

Trigonometric
Ratio
The ratio of the lengths of two
sides in a right triangle.
Sine Ratio
The ratio of the lengths of the side
opposite of an acute angle and the
hypotenuse in a right triangle.
Cosine Ratio
The ratio of the lengths of the side
adjacent to an acute angle and the
hypotenuse in a right triangle.
Tangent Ratio
The ratio of the lengths of the legs
in a right triangle.
Trigonometric
Identity
A trigonometric equation that is
true for all values of 𝜃(in its
domain) is called a trigonometric
identity.
Radian Measure
The measure of an angle in
standard position whose terminal
side intercepts an arc of length r.
