The "e" is a symbol for base-10 scientific notation. The "e" stands for ×10exponent × 10 e x p o n e n t. So -1.861246e-04 means −1.861246 ×10−4 − 1.861246 × 10 − 4. In fixed-point notation that would be -0.0001861246. This notation is pretty standard. Even Microsoft Excel understands it, not just R. Thank you.

These symbols represent concepts that, while related, are different from one another and can take some practice to get used to. Mean: The "average" number; found by adding all data points and dividing by the number of data points. Example: The mean of 4 , 1 , and 7 is ( 4 + 1 + 7) / 3 = 12 / 3 = 4 . Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). $\begingroup$ One could add that in typed math, the summation sign $\sum$ and the capital Sigma $\Sigma$ are rarely exactly the same. I'm not sure how widespread this is for handwriting though (I have different symbols, but some colleagues definitely haven't). $\endgroup$ R^+ denotes the real positive numbers.School’s out, but that doesn’t mean your kids should stop learning.

So radians are the constant of proportionality between an arc length and the radius length. θ = arc length radius θ ⋅ radius = arc length. It takes 2 π radians (a little more than 6 radians) to make a complete turn about the center of a circle. This makes sense, because the full circumference of a circle is 2 π r , or 2 π radius lengths.In math, the symbol ∈ is used to denote set membership. It is read as “is an element of” and is used to indicate that a particular element belongs to a particular set.
