Find the equation of tangent line

  1. Jun 8, 2008 #1
    1. The problem statement, all variables and given/known data

    Find equation of the tangent line at t=0


    3. The attempt at a solution

    Really dont know where to start, can someone give me the hint, dont solve it, i want to try it, just need a hint

    To find the equation of any line,you need a point on the line and the gradient on the line.

    To find the gradient at t=0,you'll need to find dy/dx (chain rule is helpful here)

    and you'll need a point on the line, you want at t=0 ,so can you find the point on the line,(x,y) when t=0?

    dy/dx=(dy/dt)/(dx/dt). Then go with rock.freak667's advice.
