Work out Curved Line Slope

For a differentiable curve, the slope at a point is the derivative evaluated at that x-value.

Formula: m = dy/dx at x = a

Geometry formulas depend on the shape and the measurements used, while physics formulas also depend on the chosen unit system. Enter only the quantities required by this relationship.

Try a simple value such as 1 for a test input where appropriate, then check whether the output has the expected unit and scale.
