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 ...

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 ...

where d is the distance and the two points are (x1, y1) and (x2, y2). The above formula requires taking the square root. As you might recall from Project 6c, you can do by just using an exponent of ...

Finding the slope of a linear function is straightforward. Furthermore the slope is the same at each point on the function. However this is not the case with non-linear functions. A non-linear ...

Abstract: Landslides in mountainous regions exhibit widespread distribution and high recurrence, posing critical threats to human safety and socioeconomic assets. Interferometric synthetic aperture ...
