HOLT ONLİNE GRAPHİNG CALCULATOR

graphing calculator

If you are plotting trigonometric functions note that you can choose degrees or radians.
This is a useful tool for studying transformations of graphs; for example look at the graphs of sin(x) and sin(2x) on the same diagram.

Enter up to 4 functions, note that you can use the blue keys on the right as well as the keyboard.
Use ^ for powers, eg x^3 for x3.

Press Graph to graph the functions. Use the Settings tab to change the axes.
To find the coordinates of points of intersection of two graphs, use the Intersection tab, select the graphs you want and then choose Find Intersection Point(s).

Below, there is some graphs. you can look them and learn better.

for example;  1st. equation: x^2+sin(x)

                  2nd. equation: sin(x)

                  3rd. equation: cos(x) 

you can see these equation's graphs and their intersection points on the below picture.

and now, you will see the setting. if you look for settings, you can change the x and y axis's coordinates.

I hope this programme has been useful guide for you about how can you use graphing calculator.

good luck :)
