This is why an implication is also called a conditional statement. Example 2.3.1. The quadratic formula asserts that b2 − 4ac > 0 ⇒ ax2 + bx + c = 0 has two distinct real solutions. Consequently, the equation x2 − 3x + 1 = 0 has two distinct real solutions because its coefficients satisfy the inequality b2 − 4ac > 0.1. R/ {0} = R −{0} = − { 0 } = the set of all x x such that x x belongs to R R and x x does not belong to {0} = the set of all x x such that x belongs to R and x ≠ 0 x ≠ 0. R R is a set, the set of real numbers. If you want R R without 0 0 in it, you cannot get this new set by writing : R − 0 R − 0. The reason is that :r is also used a polar coordinate, the distance of the point from the origin in 2 or 3 dimensional spaces. r is also used as the growth rate of any variable which grows exponentially. It is also used as the position vector of a point in physics if r is written in bold letter. In statistics also it is used. 2.The letter "R" is a common symbol in mathematics that represents the set of real numbers. Real numbers are a fundamental concept in mathematics, ... The set of real numbers, denoted by the symbol R, is also closed under a variety of mathematical operations. …Solution. P r n: P r n represent the permutation. The permutation is the arrangement of the items into some sequence or order. The number of ways of arranging r items from a set of n items is: P r n = n! n - r! C r n: C r n represent the combination. The combination is the selection of the items where the order of the items does not matter.
