摘要
介绍了抛物线(二次函数)上割线和切线平行性问题,并用数值均差法证明了抛物线(二次函数)上割线和切线平行性问题的结论,分两次推广了抛物线(二次函数)上割线和切线平行性问题的相关结论.
Abstract
The problem of secant and tangent parallelism on parabola(quadratic function)is introduced,and the numerical mean difference method is used to prove the conclusion of secant and tangent parallelism on parabola(quadratic function),and the relevant conclusions of secant and tangent parallelism problems on parabola(quadratic function)are generalized twice.
