Another way to represent the Euler line is in terms of a parameter t. Starting with the circumcenter (with trilinear coordinates cos ⁡ A : cos ⁡ B : cos ⁡ C {\displaystyle \cos A:\cos B:\cos C} ) and the orthocenter (with trilinears sec ⁡ A : sec ⁡ B : sec ⁡ C = cos ⁡ B cos ⁡ C : cos ⁡ C cos ⁡ A : cos ⁡ A cos ⁡ B ) , {\displaystyle \sec A:\sec B:\sec C=\cos B\cos C:\cos C\cos A:\cos A\cos B),} every point on the Euler line, except the orthocenter, is given by the trilinear coordinates
