The term "adaequalitas" was used to find what?

  • Maxima for functions and tangent lines to curves

  • Areas under curves

  • Lengths of curves

  • Volumes of solids

Answer

Adaequalitas, meaning "to make equal", refers to a method used by 17th-century mathematician Pierre de Fermat to determine the maxima and minima of functions and the tangents to curves. By equating the differences between ordinates to zero, Fermat was able to derive equations that allowed him to find critical points and tangents without the use of calculus, which had not yet been developed at the time.
