God I'd just type out the formula, but I'm sure u could do it using matrices somehow. sqrt(x^2+y^2+z^2)
Christ God So if you have a function defined by r(t)= cos(t)+sin(t), you can find it's magnitude at any time by doing norm(r(t)) This is probably my favourite calc shortcut 😀
God Although cool tip. If you ever get that loading wheel screen, and it doesn't go away - if you hold 'esc' it should break out of it. (Instead of having to re-set ur cas at the back)
God Christ Omg thank you so much. I never knew the ctrl+bracket vector things existed! They’re amazing : )
God Do we reckon Euler's method will show up on exam 1? I really don't want to learn how to do it by hand...
Christ God BRO THERE is a formula on the data sheet for it IT"S SO GOOOD i didn't want to learn it as well but the formula saved my ass
beep_boop Christ formula saved my ass the only helpful thing that vcaa has given us is the formula sheet (and the data book for those doing chem)
God Good luck peoples! May there be a total absence of vector proofs, and may us, the human calculators, not stuff up our simple addition!
Anthony_Watson yh I feel like I didn't do well. I made a big mistake with the partial fraction question, cos I got my values wrong for Bx+C (I got C as 0 instead of B as 0) and bcos of that I got two logs instead of an arctan. But the rest of my working was correct. How much marks out of 4 would that be?
God Actually someone on fb beat me too it: https://pdfhost.io/v/WTK0pMaWZ_2022_VCAA_Specialist_Exam_1_Solutions
