k Calculating the lntegral Value for a Given Range
Description
Use the following procedure to obtain integration values for a given range.
Set Up
1. Draw the graph.
Execution
2. Press !5(G-SLV)6(g)3( ∫ dx ). When there are multiple graphs, this causes the
selection cursor (k) to appear at the lowest numbered graph.
3. Use fc to move the cursor (k) to the graph you want, and then press w to select
it.
4. Use de to move the lower limit pointer to the location you want, and then press w.
You can also move the pointer by pressing v to display the pop-up window, and then
inputting coordinates.
5. Use e to move the upper limit pointer to the location you want.
You can also move the pointer by pressing v to display the pop-up window, and then
inputting the upper limit and lower limit values for the integration range.
6. Press w to calculate the integral value.

Function Analysis
# You can also specify the lower limit and upper
limit by inputting them on the 10-key pad.
# When setting the range, make sure that the
lower limit is less than the upper limit.
# Integral values can be calculated for rectangular
coordinate graphs only.
