Find tangent at certain angle

[tomr11694738]

Need to find tangent  at certain angle, say, 45 degrees.

Seems there's no methods in AIRealBezierSuite to calculate tangent at custom angle.

Have I missed the proper method in API?

You haven't missed it, but I'm not sure how you'd go about calculating that. I took a quick google and I couldn't even find a high level formula for calculating T from the tangent angle. Your best bet would be to find the formula for deriving the tangent angle from T and then re-arranging the formula. Not fun, I'll admit.
