-Tangent is a straight line that touches, but does not intersect, the curve at the point (2,8).

We need to find the gradient of the curve at the point (2, 8). To do this, expand the equation, diffe...

In order to analyse an artwork students should build an interpretation (an argument) about an artwork and use observations of that artwork to support their interpretation. 

An analysis is not merel...

Evaluating theories and models can be quite difficult, especially understanding where it start. One method that I like to use is called TEACUP. This helps ensure that you cover the most important elements...

Within the limited 40 minute timeframe, the most important feature to include in your essay is a coherent chain of thought, usually in the form of a thesis statement. Alongside the use of a skeletal struc...

To solve this we must use the chain rule which is dy/dt * dt/dx. Firstly, we differentiate dy/dt. For this we must use the quotient rule, this gives us dy/dt=(9te^3t - 3e^3t)/9t^2. Now for dx/dt, by subst...
