x^2 - y^2 = 1 , 1 <= x <= 2

and draw curve area between Point OAB (not triangle follow hyperbola curve path between AB for area)

Hi mathmagic. Thanks for the reply i want out locus outside the hyperbola . Pls see my attachment Area OAB but AB follow the hyperbolic path.

x² - y² ≤ 1 ∧ y ≥ 0 ∧ y x(A) ≤ x y(A)

Thanks it worked . How to draw locus between AB follow hyperbola.

@mathmagic

Is it possible to make the bold in the formula depending A (in "curve area.ggb") ?

Curve(1 / cos(t), tan(t), t, 0, acosd(1 / 2))

one solution more

works with Pathparameter and Iteration (instead of Locus)

great! this prinziple in this use was new for me (the result is undefined when undefined is add)

Thanks rami

the hyp at the rami style

Polyline(KeepIf(Min(y(A), y(B)) ≤ y(P) ≤ Max(y(A), y(B)) ∧ x(P) > 0, P, Sequence(Point(eq1, n), n, 0, 1, 0.001)))
