jmarc:
the parametric equations of a curve are:
            x=3t^2+1      y=6t

(i) obtain an expression, in terms of t, for the gradient of the curve and find the equation of the normal to the curve at the point with parameter 1/2

(ii)find the coordinates of the points of intersection of the curve and the straight line whose parametric equations are :
        x=T+5               y=2T-4

(b) the parametric equations of a curve are:
                      x=2cosz+ sinz,             y=cosz - 2sinz

write down expressions for 2x+y and x-2y in terms of z, hence determine the cartesian equation of the curve in its simplest form.

plzzzzzzz help asap


and to solve
   2^x=3^x-2



plzzzz help

I am on it

astarmathsandphysics:
here

jmarc:
wayzzzzzzzzzzzzzzzzzzzz Thanks alot ur like a flikin genius man!!!! Thanks agn !!!

astarmathsandphysics:
Do you mean 2^x=3^x-2 or 2^x=3^(x-2)

both attachmrnts in my last post download. Can you download them both?
