in the second case

is equal to The second convergence error is less than the first case. Therefore,
it is preferable to round up with more than one example. To minimize the absolute
approximation error, the following rule is used to round up positive numbers. If the
first drop-down number is less than 5, then round it by at least, if this number is
greater than or equal to 5, then round it up to the next. For example, rounding up to
a tenth is 3,647 ≈ 3.6, 2.658 ≈ 2.7 we get in rounding to one hundred 0.6532 ≈
0.65, 9,0374 ≈ 9.04 are formed. As can be seen from the foregoing, rounding
numbers simplifies calculations.
3. An absolute error is used to compare the accuracy of different
approximations of the same amount. If the convergence of different quantities is
compared, an absolute error is not sufficient. For example, the distance from
Tashkent to Fergana is 400 ± 1 km. The length of the pen is 21.3 ± 0.1 cm. In the
first case, the absolute error is no more than 1 km and in the second case no more
than 1 mm. Is it true that the length of the pen was more accurate than the distance
from Tashkent to Samarkand? Absolute error in measuring the distance from
Tashkent to Fergana not exceeding 1 km per 400 km. This means that the error is
1/400 ∙ 100% ≈0.25% of the measured size. Absolute error in measuring the length
of the pen is not more than 0.1 cm by 21.3 cm. Therefore, the error in this case is
0.1/21.3 ∙ 100% ≈ 0.47% of the measured value.
Conclusion
In conclusion, we need to pay attention to the sequence of topics in these
textbooks to ensure continuity of topics in physics textbooks and the continuity of
physics and mathematics. As we all know, a student who is well versed in
mathematics is well versed in physics.
