UNIT 1 CONTROL SYSTEM MODELING 1. Introduction Systems are sets of components‚ physical or otherwise‚ which are connected in such a manner as to form and act as entire units. Control is the effort to make systems act as desired. A process is the ac tion of a system or alternatively‚ a system in action. Humans have created control systems as technical innovations to enhance the quality and comfort of their lives. Human engineered control systems are part of automation‚ which is a feature

In mathematics‚ an algebraic expression is an expression built up from constants‚ variables‚ and a finite number of algebraic operations (addition‚ subtraction‚ multiplication‚ division and exponentiation by an exponent that is a rational number).[1] For example‚ is an algebraic expression. Since taking the square root is the same as raising to the power ‚ is also an algebraic expression. A rational expression is an expression that may be rewritten to a rational fraction by using the properties

What is algorithm design? Our text defines an algorithm to be any well-defined computational procedure that takes some values as input and produces some values as output. Like a cooking recipe‚ an algorithm provides a step-by-step method for solving a computational problem. A good understanding

slightly less ignorant 8th grader who barely made USAJMO. In 7th grade‚ I did not even know what the nine-point circle was‚ and now in 8th grade‚ I am able to prove its existence. In 7th grade‚ I could not work with polynomials and roots very well‚ and now in 8th grade‚ I can use polynomials quite efficiently. In 7th grade‚ I failed the AMC 10 with a pathetic score of 123‚ and now in 8th grade‚ I was able to score well enough on the AIME to qualify me for USAJMO. In 7th grade‚ I was complete garbage

Quadratic equation is a squared plus b squared = c squared. It’s used to find the length of three sides of a triangle. The theory is the same as any other polynomial‚ and the Greeks found out that‚ this formula holds true‚ regardless of the different types or lengths of the sides. So‚ by using the same method you use to solve a typical polynomial‚ you can solve this equation as well. For the formula to actually work you must have your equation in this form‚ quadratic=0. The 2a in the bottom of the

the value for x into the equation y = (1/2)(4) + b Now put value of y in the equation 2 = (1/2)*(4) + b Now switch b so it can be on the opposite side of the equation (1/2) *(4) + b = 2 Multiply ½ by 4 to come up with 2 2 + b = 2 Reorder polynomials b + 2 = 2 Find be value: b = 2-2 b = 0 Finally‚ to get the equation of the line use the values of the slope (m) and y-intercept (b) in the formula y = mx + b to find the equation of the line. So the end result is y = x/2 Here is a graph

expression of the form P/Q‚ where P and Q are simpler expressions (usually polynomials)‚ and the denominator Q is not zero. A rational number is any number that can be written in the form a/b‚ where a and b are integers and b ≠ 0. it is necessary to exclude 0 because the fraction represents a ÷ b‚ and division by zero is undefined. A rational expression is an expression that can be written in the form P/Q where P and Q are polynomials and the value of Q is not zero. Some examples of rational expressions:
