Hey Guys, Can anyone please help me with question 12 (a) and (b) Exercise 9B from the year 11 cambridge textbook? I've been stuck on it for ages. I don't know the relationship between 'a' and the tangent. Thanks!

Hey guys, I'm a preliminary student planning on accelerating the hsc 3-unit course throughout these holidays and next term. I would really like to get as much done as possible. What do you guys think is a good textbook to assist in doing that? I'm thinking of getting the new coroneos year 12...

Thanks Carrotsticks. Are you able to show me how to do this question? Given the point A(7,8), find the coordinates of three points P with integer coordinates such that AP = root5.

If AB is a diameter of a circle with centre Q(4,5) and A = (8,3), find B. Help please!

the question says to simplify :S

How do i solve this? sin ( 360 - x ) . tan (90 - x)

Wow, your way is very confusing Spiral O.O

Dammit! "You must spread some reputation around before giving to Carrotsticks again" :( Farr... I'll definitely remember to rep you when i can :)

OMG! I did exactly the same thing but messed up in my working out. Thanks so much Carrotsticks. + rep!!! :)

Hey guys, Can you guys please show me how to do this problem? Been stuck on it for over an hour. Solve |t + 2| + |3t - 1| < 5 Can you guys show me how to solve it graphically and/or algebraically. Thanks a lot! + rep btw :)

Ohs. Haha. Thought you would've come from a school closer to the Cabramatta region. Many of my friends go to PEAK and N&S :)

Hey such_such, may i ask, what school do you go to?

1. (a) Show that the point (-7,7) lies on the line joining A(-2,0) and B(3,-7). (b) Find the ratio in which the point divides AB. 2. Find the coordinates of the centre of a circle that passes through points (7,2), (2,3) and (-4,-1). For question 1, i already found (a) but don't know...

Hey guys! Can you guys please help me with this question? The roots of the quadratic equation x^2 - (2k+4)x + (k^2 + 3k + 2) = 0 are non zero and one is twice the other root. Calculate the value of k.

Can you guys please help me with one more question? If one of the roots of the equation 2x^2 + 3kx = 5 is 4, find the values of k and the other root. Thanks!

Thanks so much guys!

Can someone please show me how to do this question? Consider the circle x^2 + y^2 -2x - 14y + 25 = 0, (i) Show that if the line y=mx intersects the circle in two distinct points, then (1 + 7m)^2 - 25(1 + m^2) > 0 (ii) For what values of m is the line y=mx a tangent to the circle? Thanks so...

Hi guys! Well... I have been told by a few of friends that some of the girls in my that want to do medicine in uni have already started UMAT tutoring. I'm only in year 11 this year but was wondering if it is the right time to start UMAT tutoring now. Like maybe buy the papers from a certain site...

Hey guys! Do i have my maths topic test in a few days and i wanted to know, does it count towards my report or anything at all? We never got a sheet that we had to sign confirming that we know we have a test in a week or anything. All the teacher did was tell us that we are having a topic the...

Hi-5! Starting that next week at Harry's too. First time for me as well. And Spiralflex, if he teaches that at a detailed moderate pace, when does he actually start to go fast? It's been quite slow-ish kind of. LOL.
