The point A lies on the curve with equation y=x^0.5. The tangent to this curve at A is parallel to the line 3y-2x=1 . Find an equation of this tangent at A. [5 marks]

Differentiate equation dy/dx=0.5*x -0.5 Gradient is the same as the second equation 2/3=0..5*x -0.5 Solving this will give the x coordinate x = 9/16 Sub into equation for y coordinate y = (9/16) 0.5 Solve fo...
