Ignore?
Trigonometric Identites
a trigonometric equation that is true for all values of the variable for which both sides of the equation are defined.
Representatives Part
simplest domain value
Trigonometric Ratios
The values of the trigonometric are positive
Law of Sines
the sines of the angles of a triangle to the length of their opposite sides
Law of Cosines
relates the length of a side of any triangle to the measure of the opposite angle
double angle identities
trigonometric functions of angles equal to 2α in terms of α, which can simplify the functions and make it easier to perform more complex calculations, such as integration, on them.
half angle identites
trigonometric functions of angles equal to α/2 in terms of α, which can simplify the functions and make it easier to perform more complex calculations, such as integration, on them
Identity
an equation that is true for all values of "x"for which the expressions in the equation are defined.
