What is arithmetic expression . mention different types of arithmetic expressions?
An expression that represents a numeric value. Other types of expressions can represent character or Boolean values.
What is the answer when solving an equation?
In mathematics, to solve an equation is to find what values (numbers, functions, sets, etc.) fulfill a condition stated in the form of an equation (two expressions related by equality). These expressions contain one or more unknowns, which are free variables for which values are sought that cause the condition to be fulfilled. To be precise, what is sought are often not necessarily actual values, but, more in general, mathematical expressions. A solution of the equation is an assignment of expressions to the unknowns that satisfies the equation; in other words, expressions such that, when they are substituted for the unknowns, the equation becomes an identity
How can you test the equivalence of two expressions using tables and graphs?
You can test for inequality but not for equality.You can take different values of the independent variable or argument of the expression (usually denoted by x), and calculate the dependent variable or the value of the expression (usually denoted by y). These can be tabulated or shown on a graph. If the y-values for the same x-values are different, then the two expressions are different. But even if they all match perfectly, you cannot say that they are equivalent because there could be other x-values - which you did not test - for which the y-values are different.For example, considerf(x) = x^2 + 4andg(x) = x^3 - 3x^2 - 5x + 4then f(-1) = 5 = g(-1)f(0) = 4 = g(0)and f(5) = 29 = g(5)but for any other integer value of x, the values of the two expressions are different. However, your test did not pick that up.You could increase the number of points tested but there will be other expressions such that the two can match at any number of selected points and still be different elsewhere.
How can you test the equivalance of two expressions?
You can check for a few numbers, to see whether they give you the same result. This quick check can save you lots of work in the following step, in the case of complicated expressions: if, when replacing by some number, the two expressions are NOT equal, then of course they are not equivalent.However, the variables can usually have infinitely many values (Boolean algebra is an exception), in which case the only way to prove that two expressions are equivalent - meaning, equal for ALL values of the variable or variables - is to try to do some equivalence transformation to one expression, to convert it to the other expression.
Do you solve an expression the same way you solve an equation?
If we are talking about the algebraic expressions, then an expression can be simplified or be evaluated for specific values of its variables, while an equation need to be solved, in other words to find the values of the variables that make the equation a true statement. If we are solving an equation, then we can work in the same way that we can simplify an expression (since an equation is a statement that states that two expressions are equal), or factoring an expression.
How do you factorise these expressions?
In the same way that you would factorise any other expressions that do not contain an equality sign depending on the expressions of which none have been given.
What are two expressions that equal to each other?
An equation.
How do you find measure of each angle in triangle?
Important Formula: Sin(q) = Opposite / Hypotenuse Cos(q) = Adjacent / Hypotenuse Tan(q) = Opposite / AdjacentSelect what (angle / sides) you want to calculate, then enter the values in the respective rows and click calculate. If you want to calculate hypotenuse enter the values for other sides and angle.
Is an expression considered an object?
Yes, an expression can be considered an object in programming. In many programming languages, expressions produce values and can be assigned to variables, passed as arguments to functions, or used in other expressions. Thus, they exhibit characteristics of objects, such as being able to be manipulated and have properties.
Why did ENIAC and other computer gave off so much heat?
because they needed large amount of power to operate to vacuum values.
What is a mathematical sentence that uses an equal sign to show that two expressions have the same value?
When two expressions are equal to each other they form an equation.
What helps you enter data on a worksheet?
You can type data direct into cells. You can also type them into forms, which will put them into the cells. You can use other form controls to enter values in, like dropdown lists or scrollbars to increase and decrease values. You can also use validation in cells to limit what you can put into cells, which can be a help as it will reduce the amount of data entry errors you can make.
