Re: FP3 Radius of curvature of curveI have no clue!(Original post by purplesparks14)
Found this in the old P6 papers, adapted to FP3 syllabus. Do explain?
Find the exact value of the radius of curvature of the curve with equation y = arcsin x at the point where x = (sq root 2)/2.
The mark scheme gave: [ 1 + (dy/dx)^2 ] / (d2y/dx2). WHY? -

Re: FP3 Radius of curvature of curveI'm pretty certain this isn't on any FP3 syllabus. Which exam board are you on?(Original post by purplesparks14)

Re: FP3 Radius of curvature of curveEdexcel, sorry! Should have mentioned. Something similar to this is also in FP2 2006 past year. I hope it's an old syllabus thing!(Original post by hassi94)

Re: FP3 Radius of curvature of curveWell I'm pretty sure the formula should actually have a ^3/2 in there so it's not correct, furthermore I don't think it's on your syllabus. According to the specification there is absolutely no mention of radius of curvature in Edexcel FP2 or 3.(Original post by purplesparks14)
