What is the definition of a logarithm?

Back

A logarithm is the exponent to which a base must be raised to produce a given number.

Front

State the Law of Cosines formula.

Front

What is the definition of an even function?

Back

A function f(x) is even if f(-x) = f(x) for all x in the domain.

Front

What is the definition of an odd function?

Back

A function f(x) is odd if f(-x) = -f(x) for all x in the domain.
