The tangent can be determined with a collection of mathematical formulas but is most commonly determined by dividing the sine function by the cosine function. Microsoft Excel simplifies the ...

In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following ...

The graph of the quadratic function \(y = ax^2 + bx + c\) is a smooth ... Draw the graph of \(y = x^2 -x – 4 \) and use it to find the roots of the equation to 1 decimal place.
