In the applet below is intended to help you understand the connection between the graph of a function and the function itself. Recall that a function can be thought of as a machine which takes an ...

Jean Kelly from Dublin's Institute of Education is here with six videos full of great advice and tips for the exam.

Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing graphs as functions in the form of \(f(x)\) is useful ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...

Various methodsexist to compute the trigonometric functions. These include Taylorseries, Curve fitting algorithms, and the CORDIC algorithm. This tutorial describes software implementation of the ...
