You can not guarantee what the factors would have to be if the product was set equal to any other number. For example if ab = 1, then a = 5 and b = 1/5 or a = 3 and b = 1/3, etc. But with the product set equal to 0, we can guarantee finding the solution by setting each factor equal to 0.

Dot Product A vector has magnitude (how long it is) and direction: Here are two vectors: They can be multiplied using the "Dot Product" (also see Cross Product). Calculating. The Dot Product gives a number as an answer (a "scalar", not a vector). The Dot Product is written using a central dot: a · b This means the Dot Product of a and b

Product formulas for the cyclotomic v-Schur algebra and for the canonical bases of the Fock space Dedicated to Gus Lehrer on the occasion of his 60th birthday Author links open overlay panel Toshiaki Shoji Kentaro Wada The algebraic products on this page are used all the time later in this chapter, and in a lot of the math you will come across later. They are "special" because they are very common, and they're worth knowing. If you can recognize these products easily, it makes your life easier later on.
Dec 19, 2018 · There are four formulas that can be used to break up a product of sines or cosines. These product-to-sum formulas come from equation 48 and equation 49 for sine and cosine of A ± B. First let’s develop one of these formulas, and then we’ll look at an application before developing the others. Take the two formulas for cos(A ± B) and add them:

sum to product formulas,trigonometry,half angle formulas,C+D formula Sum To Product Formulas In this page sum to product formulas we are going to see four formulas which are used frequently in trigonometry. ..., 5, 3, 1,1,3,5,... . Here are six useful facts regarding the sum and product of even and odd integers. Fact 1: The sum of two even integers is an even integer. Fact 2: The sum of two odd integers is an even integer. Fact 3: The sum of an even integer and an odd integer is an odd integer.
Determinant formulas and cofactors Now that we know the properties of the determinant, it’s time to learn some (rather messy) formulas for computing it. Formula for the determinant We know that the determinant has the following three properties: 1. det I = 1 2. Exchanging rows reverses the sign of the determinant. 3. Algebra (from Arabic: الجبر, transliterated "al-jabr", meaning "reunion of broken parts") is a part of mathematics (often called math in the United States and maths or numeracy in the United Kingdom). It uses variables to represent a value that is not yet known. When an equals sign (=) is used, this is called an equation.
The vector product of a and b is deﬁned to be a× b= |a||b| sinθnˆ where |a| is the modulus, or magnitude of a, |b| is the modulus of b, θ is the angle between a and b, and nˆ is a unit vector, perpendicular to both a and b in a sense deﬁned by the right hand screw rule.
To display part of a formula using display style, do the same thing, but use \displaystyle instead.
