In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in the ...

Microsoft's Excel software for Mac can execute a number of statistical functions, including finding the y-intercept of the line formed by a set of data points. Excel's intercept function takes the ...

Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...

In the last lesson, we derived the functions that we help us descend along our cost functions efficiently. Remember that this technique is not so different from what we saw with using the derivative ...
