Math Software -> Graph Calculus -> Tangent Line and Normal Line

Visual Calculus has the ability of creating tangent line and normal line of 2D curve. The following figure shows five tangent lines and five normal lines on the graph of equation y=sin(x).

The calculating results are shown in Result Editor
