👉 In mathematics and physics, "unbent" refers to a curve that is always at an angle of 90 degrees with respect to its own tangent line. This means that if you were to trace out the curve on a graph or plot it in space, you would find that it never crosses itself. For example, consider the function y = x^2 - 4x + 3. This is a parabola that opens upwards and has its vertex at (1,
