Using the Classpad to find Integrals

To find the indefinite integral math \displaystyle{\int} \dfrac{1}{\sqrt{25-x^2}} dx math

In the MAIN screen, bring up the virtual keyboard and select the **2D** keyboard. Then select CALC from the bottom row of the virtual keyboard.

You can now select the **Integration** form

The integral we want to enter has a fraction, so use the backarrow in the bottom row of the virtual keyboard and select the fraction form.

Now enter the function math \displaystyle{\int} \dfrac{1}{\sqrt{25-x^2}} dx math

Since this is an indefinite integral, leave the slots for the terminals empty but don't forget to enter the **x** in the slot for the **dx** term.

You can use the square root form, from the same section of the keyboard, or the square root symbol from the MTH section of the keyboard (and use brackets).

Finally press EXE and you should get the result as shown:

Notice that the calculator does NOT put in the **+ c** term. You would need to add this when writing down your solution. .
