Please see below. Use a bracket (sometimes called a square bracket) to indicate that the endpoint is included in the interval, a parenthesis (sometimes called a round bracket) to indicate that it is not. Brackets are like inequalities that say "or equal" parentheses are like strict inequalities. (3,7) includes 3.1 and 3.007 and 3.00000000002, but it does not include 3. It also includes numbers ...
I would say: 2(Z-12)=10 Twice means two times; Difference means subtraction. Probably: Z=17
No. They have no special significance. All of these are simply used by convention to refer to a function. For example, f(x)=e^x, a(x)=e^x, and z(x)=e^x all mean the same thing. However, some notations mean only one thing. For example, zeta(s) refers to the Riemann zeta function: sum_(n=1)^oo1/n^s (See this link for more info: Riemann zeta function) In general, though, functions that describe ...
It will make sense. over time.) Answer link. Read below. Mainly used for "Difference between two given values", it is used a lot in derivatives. If we have any line on a graph, its slope is (y_2-y_1)/ (x_2-x_1) This means "the change in y value over the change is x value" which can be rewritten as (Deltay)/ (Deltax) Calculus stuff...
It's undefined. 1/0 = "undefined" You tend to see "does not exist" when you encounter imaginary numbers in the context of real numbers, or perhaps when taking a limit at a point where you get a two-sided divergence, such as: lim_ (x->0^+) 1/x = oo lim_ (x->0^-) 1/x = -oo Therefore: lim_ (x->0) 1/x => "DNE" graph {1/x [-10, 10, -5, 5]} This ...
For factoring polynomials, "factoring" (or "factoring completely") is always done using some set of numbers as possible coefficient. We say we are factoring "over" the set. x^3 -x^2-5x+5 can be factored over the integers as (x-1)(x^2-5) x^2-5 cannot be factored using integer coefficients. (It is irreducible over the integers.) over the real numbers x^2-5 = (x-sqrt5)(x+sqrt5) One more: x^2+1 ...
Graphically, limits do not exist when: there is a jump discontinuity. (Left-Hand Limit ≠ Right-Hand Limit) The limit does not exist at x = 1 in the graph below. there is a vertical asymptote. (Infinit Limit) (Caution: When you have infinite limits, limits do not exist.) The limit at x = 2 does not exist in the graph below.
1 Answer. A causal relationship means that one event caused the other event to happen. A correlation means when one event happens, the other also tends to happen, but it does not imply that one caused the other. A causal relationship means that one event caused the other event to happen. A correlation means when one event happens, the other ...
Mean is the average of given sets of numbers. You should add the numbers up then divide by the number of the numbers. Median is the number in the middle when you order the numbers in an ascending order. If there are two numbers in the middle, you should take the average of those two numbers. Mode is the number which is repeated the most in the set. For example, let's say we have a set of 8,4,1 ...
Other than that exception, sum, difference, product, and quotient are just fancy words for adding, subtracting, multiplying, and dividing respectively. There are the simple symbols: a+b,a-b,axxb, a-:b (or a/b). There is a special symbol for difference used in some math and science equations: Deltax. This means there is a final value and an ...
