Projectile motion questions are common in A-level physics as they combine the idea of resolving vectors into their components and using the equations of motion ('suvat' equations) to calculate unknown ...

Personal statements involve cramming your achievements, hobbies and personality in a mere 4000 characters. At this nerve wracking time it is most likely very difficult to see what you should include or...

From the addition formula, we know that:

Rcos(x-c) = Rcos(x)sin(c)+Rsin(x)cos(c)

Therefore:

acos(x)+bsin(x) = Rcos(x)cos(c)+Rsin(x)sin(c)

If we e...
