    some problems in year 11 going into hsc.

    Hello, thanks for the responses, was wondering is there anything said on the Board Of Studies to do with this? Whether or not a teacher can force you to take part in a course. I cant find any, only previous posts about this topic

    some problems in year 11 going into hsc.

    Hi, currently im at 12 units for the preliminary course, and for my HSC subjects im wishing to drop 2 subjects (worth 3 units) and pick up Maths Ext 2. which then will bring me to a total of 10 units. However the head maths teacher in my school told me it was an invitational subject and that i...

    cant do curve question

    The equation of a parabola is of the form y=kx^2. If the line 8x-y-4=0 is a tangent to the parabola, find the value of k. thanks.

    Few past paper questions i cant do

    Thanks alot, im still lost for the circle locus question though, i have no idea where to start on that question, do i use a cartesian equation to solve it?

    Few past paper questions i cant do

    1. For what values of 'b' is the line y=3x+b, a tangent to y=X^3 ? 2. AB is a chord of length 16 units of the circle x^2 + y^2= 100 and P is the midpoint of AB. Determine the locus of P. 3. b) of attachement thanks in advance

    locus question

    im sorry i didnt get that last bit, would you please elaborate?

    locus question

    If P(x,y) is any point on the line y=4x+3 show that the midpoint 'M' of OP has coordinates (x/2,1/2(4x+3)). Hence find the locus of M. (O is the origin), dont understand when it asks for the 'locus of M'.

    another locus question

    thank you

    another locus question

    Given two points A(3,-2) and B(-1,7), find the equation of the locus of P(x,y) if the gradient of PA is twice the gradient of PB. Im unsure on how to solve this question.

    locus question

    hi im a little confused, Find the equation of the locus of a point that moves so that its distance from the line 3x+4y+5=0 is always 4 units.

    Absolute Value function question

    I'm unsure about question D. Would anybody mind explaining how to do it?

    Trig quadrant question

    Ah hold on I think I misunderstood something, I can't seem to get 4 answers where theta is between -180 and 180 degrees.

    Trig quadrant question

    Thanks

    Trig quadrant question

    Would you mind working out the question? I'm still a little confused
