diagram request

It would be great if someone drew a diagram of:

For any point $(x, y)$ of the differential curve, construct the auxiliary triangle with vertices $(x, y), (x, 0)$ and $(x - 1, 0)$ . The hypotenuse of this right triangle intersects the $X$ -axis making an angle the value of whose tangent is $y$ . This hypotenuse is parallel to the tangent line of the integral curve at $(X, Y)$ that corresponds to $(x, y)$ .
