Find the standard matrix for a linear transformation
(After each step you have in each row a vector and its image. This is because of linearity.) If you manage to obtain the identity matrix on the left, then you know the images of the vectors from the standard basis, which is sufficient to obtain the matrix of your linear transformation. (Since you're using column vectors, the result is the ...
can fractions be done on a regular caculator?
2014年7月3日 · But if you want an immediate answer without any extra thought or scratch-work, you need a calculator that can handle fractions. Note that not all scientific calculators can handle fractions natively. The ones that can have a special fraction key, e.g. the Casio that I used a long time ago in school had an "a b/c" key that allowed you to enter ...
How do I combine standard deviations of two groups?
2018年10月26日 · According to the second formula we have Sb = √(n1 − 1)S21 + (n2 − 1)S22 = 535.82 ≠ 34.025. To be fair, the formula S′b = √ (n1 − 1) S2 1 + (n2 − 1) S2 2 n1 + n2 − 2 = 34.093 ≠ 34.025 is more reasonable. This is the formula for the 'pooled standard deviation' in a pooled 2-sample t test. If we may have two samples from ...
Finding the standard deviation of a set of angles.
1. Your first number is 39 + 15 60 + 1 602 = 39.250277777 … 39 + 15 60 + 1 60 2 = 39.250277777 …. Deal similarly with the others. And remember to do as little rounding as possible at least until the last step. Rounding should always wait until the last step except when you know how much effect it will have on the bottom line.
Convert boolean expression into SOP and POS

How to know when to put calculator in radian or degree mode?
I should mention that for those first 4 problems, I think the point is actually not to use a calculator. The second part says ¨Find the function values. Round to four decimals places.¨: Cos 111.4° degree mode because there is a degree symbol. Sin( …
Standard deviation sig figs - Mathematics Stack Exchange
2020年5月30日 · If your data is rounded to one decimal, each item is uncertain by ±0.05 ± 0.05. The variance of the uniform distribution of total width 0.1 0.1 is 1 12 ⋅0.12 1 12 ⋅ 0.1 2. The variance of the sum of N N items is then N1200 N 1200. The standard deviation of the mean is about 1 35 N√ 1 35 N. You can use this as a guide on how many ...
