# Help needed to calculate a specific curve with specific rotation

Hi all,

I am trying to code a specific curve with a specific rotation. I am not a great mathematician... At all... Tried searching for solutions for a few hours, but I'm affraid I do not find any solution.

So, a small picture to illustrate first: http://imgur.com/gallery/8T4Tb

This is an eighth of a circle, radius of 9, beggining is (0,0)

The end is now at about 6.364, -2.636. But I need this same curve, with a 45° direction at the end, but ending at aexactly 6.0,-3.0.

Could any of you show me how to do this? I need to be able to calculate precisly any point on this curve & its exact length. I would suppose using some kind of eliptical math could be a solution? I admit my math class are reaaally far now and have now good clue for now...

Thank for any possible help
