Define a class called Rational for rational numbers. A rational number is a number that can be represented as the quotient of two integers. For example, /2, 3/4, 64/2, and so forth are all rational numbers.Represent rational numbers as two private values of type int, numfor the numerator and den for the denominator. The class has a default constructor with default values (num = 0,den = 1), a copy constructor, an assignment operator and three friend functions for operator overloading...

Write a rational number class in C++. Recall a rational number is a rational number, composed of two integers with division indicated. The division is not carried out, it is only indicated, as in 1/2, 2/3, 15/32. You should represent rational numbers using two int values, numerator and denominator. A principle of abstract data type construction is that constructors must be present to create objects with any legal values. You should provide the following two constructors: one constructor to make...

Is rational number divided by an irrational number equal to irrational number or rational number?

Is rational number divided by an irrational number equal to irrational number or rational number? for example such as ( 5 / 2pi )

Numeric responses must be either an integer (if exact) or a real number with three decimal places, with the least significant number rounded. Do not use commas. If there are units, the integer part must be between 1 and 999. Use the following units: Ohm, kOhm, mOhm resistors, etc. Conductances: S, mS, MS, etc. Voltage: V, kV, mV, MV, etc. Current: A, mA, kA, uA, nA, etc. Power: W, mW, kW, uA, pW, etc. Time: s, hrs, ks, ms, etc....

Define the following predicates: Real( x) = “x is a real number”. Pos(x) = “x is a positive real number.” Neg(x) = “x is a negative real number.” Int(x) = “x is an integer.” Rewrite the following statements without using quantifiers. Determine which statements are true or false and justify your answer as best you can. a) Pos(0) b) ∀x, Real(x) ∧ Neg(x) → Pos(−x) c) ∀x, Int(x) → Real(x) d) ∃x such that Real(x) ∧∼ Int(x)

This problem involves a periodic system: while t can be any real number, the dependent variable θ(t) ∈ [0, 2π). Consult chapter 4 of Strogatz. Consider the equation θ ̇ = μ + sin θ. (a) Draw phase portraits for different values of μ, find the bifurcation values of μ, and describe the fixed points and their stability in each regime. (b) Now consider specifically the case where μ is just slightly less than 1: what is true about the...
