Which curve's tangent properties was Barrow the first to calculate?
Kappa curve
Sine curve
Parabolic curve
Logarithmic spiral
Answer
The kappa curve is a curve with the equation y = k / x, where k is a constant. Barrow was the first to calculate the tangent properties of this curve. He found that the tangent of the curve at any point is equal to the slope of the line joining that point to the origin.
