I have another question i'm stuck on, so i thought i'd post it here as well If a rocket's acceleration is given by a= -k/x^2, where x is the distance from the centre of the earth, and if the rocket starts from rest at the surface of the Earth (radius 6400km), find an equation for the velocity...

hey guys. I'm having trouble with this topic, so could you pls explain your steps as you go the velocity of a particle is given by v=1/(15x^2) m/s and the particle is initially at the origin. find it's displacement after 4 seconds to 2.d.p

Find the general solutions to: a). cos4x +cos2x = 1 b). cos3x= cosx any help would be good !

Hey Guys So i currently do extension 1 and 2 maths at high school and I've kinda been considering doing actuary at uni, but i was wondering, what kind of maths does it involve? And what maths should you be particularly good at in high school to help with this course thanks!!

Ooh right of course haha. When I did it, I found the x-intercepts and i forgot to draw one of them (cant remember atm) as the double root. But thankyou heaps!

Calculate the area of the region bounded by the curve y=2x^2(4-x) and the x-axis. Thanks :)

For ancient history I'd suggest Antiquity 1. This was really helpful and followed our school work perfectly

Hey guys! How do I write sin theta/2 and cost theta/2 using the T formulas?? Any help would be great ☺ Sent from my SM-G920I using Tapatalk

Note that in Q25, to to the distance of the point P to the line y=-1, you can also do the perpendicular distance formula as that is quicker

Q24. SO the gradient of PA is y + 2/x-3, simply by using the formula. similarly, the gradient of PB is y-7/x +1 Now gradient PA=2PB therefore, y+2/x-3 = 2(y-7)(x+1). Now cross multiply the demoninators and you'll get: (y + 2)(x+1)= 2(y-7)(x-3). Expand this and you'll get: xy + y +2x +2=...

Hey guys! I don't actually have a maths problem, I was just wondering if you'll ever get asked in extension 1 maths to use Simpson's rule or the trapezoidal rule for integration? Thanks

i believe so. Thats what my teachers tell me

Hey guys! This is a pretty general question I guess haha, but I was curious as to how the HSC answer booklets work? Cus i remember my sibling telling me and it sounded pretty confusing at the time haha Thanks
