Why you pass arguments to function in c plus plus?
You pass arguments to functions because that is how you tell the function what you want it to do. If you had, for instance, a function that calculated the square root of something, you would pass that something as an argument, such as a = sqrt (b). In this case sqrt is the function name, b is passed as its argument, and the return value is assigned to a.
What number will the function return if the input is 12.2?
36.6
Give the six trigonometric function of 120?
sin(-120)=sqrt(3)/2 cos(-120)=-1/2 tan(-120)=-sqrt(3) csc(-120)=2/sqrt(3) sec(-120)=-2 cot(-120)=-1/sqrt(3)
What is an example of a wrong function equation?
An example of a wrong function equation is f(x) = sqrt(x) for all non-negative x.
What is the square root of 72 using radicals?
sqrt(72) = sqrt(36*2) = sqrt(36)*sqrt(2) = 6*sqrt(2).sqrt(72) = sqrt(36*2) = sqrt(36)*sqrt(2) = 6*sqrt(2).sqrt(72) = sqrt(36*2) = sqrt(36)*sqrt(2) = 6*sqrt(2).sqrt(72) = sqrt(36*2) = sqrt(36)*sqrt(2) = 6*sqrt(2).
What does sqrt function return?
square root of the argument

What is the trigonometric function sec?
The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).
How do you use return function?
return;orreturn ;PS: not function, statement!
What is the function of square root in C programming?
it is sqrt in header math.h
The function h(x) is a transformation of the square root parent function, f(x) = \sqrt xf(x)= x . What function is h(x)?
The square root function is one of the most common radical functions, where its graph looks similar to a logarithmic function. Its parent function will be the most fundamental form of the function and represented by the equation, y =sqrt {x}.
How do you know if a graph is a function or not?
As long as the line represented on the graph has no vertical segments then it may be represented by a function. * * * * * That is not enough. y = sqrt(x) has no vertical segments but it is not a function in the mathematical sense. A function cannot map an x value to more than one y value. Clearly, the above function maps x to -sqrt(x) and +sqrt(x) and so is not a function. However, there no vertical segment. No matter how close you get to x = 0, there is still a curve and the segment is not vertical.
What number will the function return if the input is 12.2?
36.6
What is a return statement used for?
It means end the function. Functions automatically end when execution reaches the end of the function, but you can return from a function at any point within the function with a return statement. If the function returns a value to its caller, you must provide a reachable return statement along with the value you wish to return.
Is y equals the square root of x plus 27 a function of x?
No, without any restriction in the range, it is not a function. If it were a function, each value of x could have at most one value of y.However, suppose x = 0. Then y = sqrt(0 + 27) = sqrt(27) = -3*sqrt(3) and + 3*sqrt(3) that is, there are two possible values of y for x = 0. The same is true for each value of x > -27.
Write a program to return a function using class in C Plus Plus?
Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.
When writing a function does the order matters?
Depending on what you want to do, yes, it may depend. For example, when applying one function after another, the order most certainly matters. For instance, sin(sqrt(x)) is generally not the same as sqrt(sin(x)).
