integration calculation decreases by a factor of ten for each additional digit, specified in the display format. Example: Changing the Accuracy. For the integral of Si(2) just calculated, specify that the result be accurate to four decimal places instead of only two. Keys: Display: Description: z ž { } 4 ) . Specifies accuracy to four decimal places. The uncertainty from the last example is still in the display. 9 9 )   Rolls down the limits of integration from the Z- and T-registers into the X- and Y-registers. { G 1%2ª% Displays the current equation. { ) X !!Calculates the result. Z ) . Note that the uncertainty is about 1/100 as large as the uncertainty of the SCI 2 result calculated previously. z ž {%} 4 ) . Restores FIX 4 format. z Restores Degrees mode. This uncertainty indicates that the result might be correct to only four decimal places. In reality, this result is accurate to seven decimal places when compared with the actual value of this integral. Since the uncertainty of a result is calculated conservatively, the calculator's approximation in most cases is more accurate than its uncertainty indicates. 8-8 Integrating Equations File name 32sii-Manual-E-0424 Printed Date : 2003/4/24 Size : 17.7 x 25.2 cm
