First, we need to recognise which equation to use. From the Physics Equation Sheet, we can see that the correct equation here is that dQ=mcdT, where dQ is the Energy transfer. Using this equation...

All exponential equations can be reduced to the form m=m₀e^kt, where m₀ is the initial mass. This means for our equation the initial mass is 250g. If the mass has doubled i...

For example, y = 3x³ + 9x² + 2. Determine the stationary points and their nature.

Let's remind ourselves what a stationary point is, and what is meant by the ...

Aerobic respirtation is the process by which glucose and oxygen go to form carbon dioxide and water. The reaction occurs in the mitochondria. The process is needed to release energy. The chemical equation...

We know that having cos and sin functions in a question is going to cause us problems - we need a single function of x. So, step 1, we need to rewrite sin or cos in terms of the other. How do we choose wh...
