We can calculate the gradient of a tangent to a curve by differentiating. In order to find the equation of a tangent, we: Differentiate the equation of the curve Substitute the \(x\) value into ...

Any line with a gradient of 3 will be parallel to \(y = 3x + 7\). Two examples are \(y = 3x - 2\) and \(y = 3x + 11.6\). Find the equation of a straight line that is perpendicular to \(y = 2x + 1\).

Here we look at the same problem, but at the other end of the conceptual gradient ... equation is also a useful model for developing intuitive ideas about populations. The classic example is ...

As we discussed in the practical class, the Nernst equation is able to give a value for the voltage that must exist across the membrane in order to balance a chemical gradient that exists for the ion ...
