Given information: Consider the inequality 0<f 1(θ)<f 2(θ) on the closed interval [α,β] and the integral ∫ aAf 2(θ)∫ δ1(θ)drdθ. The objective is to explain the meaning of integral in the rectangular θr -coordinate system and in the polar coordinate system. Step 2. Calculation: Consider the rectangular θr -coordinate system.live councils inquiry ( part1) public hearing of president commission on local councilsA math expression is different from a math equation. The difference between expressions and equations is that an expression signifies a combination of numbers, variables, and operation symbols whereas an equation will always use an equal (=) operator between two math expressions. Also both sides of the “equal to” sign have the same value.

The greater than or equal to symbol is used to represent inequality in math. It tells us that the given variable is either greater than or equal to a particular value. For example, if x ≥ 3 is given, it means that x is either greater than or equal to 3. It defines a range of values that x can take which starts from 3 and goes up till infinity. 1.Mar 18, 2011 · Sorted by: 90. It is borrowed from computer programming: it means that the item on the left hand side is being defined to be what is on the right hand side. For example, y:= 7x + 2 y := 7 x + 2. means that y y is defined to be 7x + 2 7 x + 2. This is different from, say, writing. 1 =sin2(θ) +cos2(θ) 1 = sin 2 ( θ) + cos 2 ( θ)

The equal sign with two lines means something is equal to something. Example: a = 3, b = 9. The equal sign with three lines means that something is identical or similar to something but not necessarily equal. Thus, a triple equals sign means equivalent. The equivalent is not the same as ‘equals’.

These symbols have the same meaning; commonly × is used to mean multiplication when handwritten or used on a calculator 2 × 2, for example. The symbol * is used in spreadsheets and other computer applications to indicate a multiplication, although * does have other more complex meanings in mathematics.

t. e. In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. increment: An increment is a small, unspecified, nonzero change in the value of a quantity. The symbol most commonly used is the uppercase Greek letter delta ( ).

Writing {\displaystyle x\in A} x\in A means that "x is an element of A". Equivalent expressions are "x is a member of A", "x belongs to A", "x is in A" and "x lies in A". The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A".

The := symbol is used in math to define the value or meaning of a variable or constant. This can be done in a variety of ways, depending on the context and the specific needs of the problem. One common way to use the := symbol is to assign a specific value to a variable. For example, we might say “x := 5,” which defines the value of x to be 5.
