The tangent command draws tangents to surfaces.
Example.
Define the function g:
Input:
then the graph G of g and a point A on the graph:
Input:
| G:=plotfunc(g(x),x):; |
| A:=point(1.2,g(1.2)):; |
If you want to draw the tangent at the point A to the graph
G, you can enter:
Input:
or:
Output:
For the equation of the tangent line, you can enter:
Input:
Output:
| y=2.4 x−1.44 |
