Velocity can never be negative and the RCos(x-a) graph is shifted to the right so you can get 1

Even if the papers hard, they're not going to ask something that's not part of C3.
We'll all be fine, we just have to stay calm and remember the maths we do know.

You have speed which is scalar so it can't be less than 0

guys for domain and range, are there any patterns/rules for
lnx (plus a constant or whatever) and swell for
e^x ????

like i know lnx can't be 0 or less…
but what about e^x…

i could be possibly getting full marks but missing out on these stupid range and domain marks
