Specifically, this means that the domain of sin x is all real numbers, and the range is [-1,1]. Want to join the conversation?

Sinx domain

Wiki User. Use the function to find the image of each point in the domain. The set of values that you get will be the range. If the function is well behaved, you will not have to try each and every value in the domain. The domain is, but the range need not be. The domain and range are the x and y coordinates of the dot, respectively. The domain is any subset of the real numbers that you choose, The range is the set of all values that the points in the domain are mapped to. Describe how to find the domain and range of a relation given by a set of ordered pairs. What is the range of the function? You need to know the domain in order to find the range. The range of a function is the set of all of the possible values that it can take on as an output value. You find the range by inspecting the function and seeing first what the domain is, and then what the range would be for that domain. The domain, then, is the set of all of the possible values that it can take on as an input value. Log in. Study now See answer 1.

I mean sinx domain I agree, as you keep increasing theta like this we just keep going around and around the circle and this pattern kind of emerges, sinx domain, but what happens when we go in the negative direction?

Some values are excluded from the domain and range of trigonometric functions depending upon the region where the trigonometric function is not defined. In this article, we will explore the domain and range of trigonometric functions using table, and graph, and domain and range of inverse trigonometric functions along with examples for a better understanding. The domain and range of trigonometric functions are the input values and the output values of trigonometric functions , respectively. The domain of trigonometric functions denotes the values of angles where the trigonometric functions are defined and the range of trigonometric functions gives the resultant value of the trigonometric function corresponding to the domain. We know that sine function is the ratio of the perpendicular and hypotenuse of a right-angled triangle. The domain and range of trigonometric function sine are given by:. We know that the cosine function is the ratio of the adjacent side and hypotenuse of a right-angled triangle.

Sinx domain

The sine of an angle is a trigonometric function that is denoted by sin x, where x is the angle in consideration. In a right-angled triangle, the ratio of the perpendicular and the hypotenuse is called the sine function. In other words, it is the ratio of the side opposite to the angle in consideration and the hypotenuse and its value vary as the angle varies. The sine function is used to represent sound and light waves in the field of physics. In this article, we will learn the basic properties of sin x, sine graph, its domain and range, derivative, integral, and power series expansion. We will solve a few examples using the sine function for a better understanding of the concept. The sine of an angle in a right-angled triangle is a ratio of the side opposite to an angle and the hypotenuse.

So you're gonna go back to this point right over here, and you could keep going. We're just going more and more around the circle. A sine wave will continue into infinity, unless you restrict its domain. Is there just not any end behavior since it's periodic? I agree that opp is 1, but what is the hypotenus? If you're seeing this message, it means we're having trouble loading external resources on our website. Well that's the point zero comma one. What happens when theta is equal to two pi? Suggested Exams. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Answers. So sine of negative pi over two is negative one, and we see that it just continues.

Wolfram Alpha is a great tool for finding the domain and range of a function. It also shows plots of the function and illustrates the domain and range on a number line to enhance your mathematical intuition. Enter your queries using plain English.

We intersect the terminal side of the angle intersects the unit circle right over here, and so based on that what is sine of three pi over two? The domain, then, is the set of all of the possible values that it can take on as an input value. So then you're gonna get back to sine of theta being equal to one. And just as a reminder, the domain are all of the inputs over which the function is defined, or all of the valid inputs into the function that the function will actually spit out a valid answer. It looks something like this. A bag contains 7 white, 6 red and 9 black balls. Sine is the Y coordinate, so this right over here is sine of pi. So, let's go back to the question. If the function is well behaved, you will not have to try each and every value in the domain. Flag Button navigates to signup page. Let's come full circle here. So sine of negative pi over two is negative one, and we see that it just continues. So, on the unit circle this is X, and this is Y, or you could even do this, as the, well, we can just use X or Y, and so for a given theta we can see where that angle entered to the terminal side of the angle intersects the unit circle, and then those, the Y coordinate of that point is going to be sine of theta.
