Quiz Chapter 01.03 Sources of Error MULTIPLE CHOICE TEST (All Tests) SOURCES OF ERROR (More on Sources of Error) INTRO TO SCIENTIFIC COMPUTING (More on Scientific Computing) Pick the most appropriate answer 1. Truncation error is caused by approximating irrational numbers fractions rational numbers exact mathematical procedures 2. A computer that represents only 4 significant digits with chopping would calculate 66.666\times33.333 as 2220 2221 2221.17778 2222 3. A computer that represents only 4 significant digits with rounding would calculate 66.666\times33.333 as 2220 2221 2221.17778 2222 4. The truncation error in calculating {f}'\left(2\right) for f\left(x\right)=x^{2} by {f}'\left(x\right)\cong\dfrac{f\left(x+h\right)-f\left(x\right)}{h} with h=0.2 is -0.20 0.20 4.0 4.2 5. The truncation error in finding\, \displaystyle\int_{-3}^{0}x^{3}dx using LRAM (left end point Riemann approximation) with equally portioned points -3<0<3<6<9 is 648 756 972 1620 6. The number 1/10 is registered in a fixed 6 bit-register with all bits used for the fractional part. The difference gets accumulated every 1/10th of a second for one day. The magnitude of the accumulated difference is 0.082 135 270 5400 Loading …
