First find the nth term of the sequence. Start by finding the difference between each term:

3, 5, 7, 9, 11 - the difference between each is 2 therefore it is 2n but this alone gives the sequence: 2...

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 ...

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...
