    In C3, how would you find the domain of fg(x), given that for f(x): x>0, and for g(x): x e R

    Edit: Think I've just realised it's only the domain of g

    Is there ever any point in using the remainder theorem rather than just doing long division? I dont think ive ever used the remainder theorem yet and I dont think I know how to. Should I learn it?

    Edit: meant to post this in the C3 thread

    for part b you find dy/dx and enter your value for t giving you the gradient of the tangent .Once you have the gradient put the coordinates for B and the gradient into y-y1=m(x-x1) and you should end up with 9x-4y-135

    hope that helps

    and for part c just enter x=t^2+2t and y=t^3-9t into 9x-4y-135=0 and solve for t and put that value of t back into x and y hope that helps
