Hello, sir!

Before I solve your question, I'd just like to say you made an excellent investment. Luckily for you, doing the bare minimum in terms of revision, will still get you an A!

Now, with your question, you'd need to work out the parametric form of the parabola.
You then go to 'Menu'
then 'Conics'
and then click F3 for parametric

You made an A* investment, pun intended.

Huh lol no!

I have completed all of the questions from questions by topic on physics and maths tutor and I m self teaching myself. The book method does indeed take a long time which is crucial for the exam.

How do I check with edexcel exam board which graphical calculators are allowed?
