Finding limit of a function

To find the limit of a function as x - value approaches zero (0), Double click you will get new window

Now , edit the - ∞ by changing it to 0 ( zero). This action means you want to know the limit of the function as x - value approaches 0 (zero). To insert the infinity symbol ∞ click the icon , then select the infinity symbol.

Now apply lesson you have learned. Type exactly the new function and find its limit as x value approaches zero (0). Double click . Then type exactly f(x)=5sinx/x. Then press ENTER.

For now don't worry about the area bounded. That area is valid only for the old function x^3+6x^2+11x + 6.

Next step double click You should get .This time you need to edit the function to reflect the new function 5sinx/x.
