For each of these functions we will:

sine (sin) cosine (cos) tangent (tan) arcsine (arcsin) arccosine (arccos) arctangent (arctan) base 10 logarithm (log) natural logarithm (ln) exponential with base e(exp ore)^{ x}square root (sqrt) power ( y)^{ x}

- explain why the function is important
- state the domain and range of the function
- show a graph of the function
- list special values of the function
- give an algorithm to calculate the function
- show how to extend the function to the complex numbers
- explain how to use the function in the Algebra Coach
