Rational fractions are of the form a/b, in which a and b are integers and b≠0. In this exercise, by "fractions" we mean rational fractions. Suppose a/b and c/d are fractions. Arithmetic operations on fractions are defined by the following rules: Fractions are compared as follows: a/b op c/d if ad op bc, in which op is any of the relational operations. For example, a/b < c/d if ad > bc. Design a class—say, fractionType—that performs the arithmetic and relational operations on fractions. Overload the arithmetic and relational operators so that the appropriate symbols can be used to perform the operation. Also, overload the stream insertion and stream extraction operators for easy input and output. Write a C++ program that, using the class fractionType, performs operations on fractions. Among other things, test the following: Suppose x, y, and z are objects of type fractionType. If the input is 2/3, the statement should store 2/3 in x. The statement should output the value of x + y in fraction form. The statement should store the sum of x and y in z in fraction form. Your answer need not be in the lowest terms.

Robots with telescoping arms are sometimes used to perform tasks (e. g., welding or placing screws) where access may be difficult for other robotic types. during a test run, a robot arm is programmed to extend according to the relationship r = 3 + 0.5cos(4θ) and the arm rotates according to the relationship θ=−π4t2+πt , where r is in feet, θ is in radians, and t is in seconds. use a computer program to plot the path of tip a in x and y coordinates for 0 ≤ t ≤ 4s.
