Need help on 2 Maths Questions

For question 2), use A = x and B = 1, and solve from there. Use the formulas for cosh and sinh to work out what cosh(1) and sinh(1) are.

I can't remember how you'd solve question 1), I think it's just some result that you have to memorise, have a look through your textbook.

Got question 2, thanks

I did have a look in the textbook for the vector question but there's nothing there :/

I think I've got the answer to the vector question now! But would you mind spotting where I got part e correct? I got the other answers right but not this one :/

Decided to do the entire question to help, here's my answers for parts d and e:

Also, thanks for the follow!

Ah I see what you've done, thank you! If I could rep you again I definitely would

Do you have any advice on how to get better at questions like those? You seem to be really good at it
