Slope Field Template
This template shows a slope field for the differential equation dy/dx = (6x+5y)/(4y-5x) and one of its solutions, 3x^2 + 5xy - 2y^2 = -8. Slopes are defined by the multivariable function F(x, y). You may also adjust the size of the slope field by changing xmin, xmax, ymin, and ymax.

Tangent and Secant Lines
|
Move the blue slider to change the x-coordinate of point A. Watch how this affects the tangent line. Click on "Show Secant" to see the secant line through point A and a new point B. Move the green slider to change the x-coorinate of point B. What happens to the slope of the secant line as B gets closer to A from the left? from the right? Finally, you can click inside the box to change the function f(x). |
