Welcome to sin 720°, our post aboutthe sine of 720 degrees.
For the sine of 720 degrees we use the abbreviation sin for the trigonometric function together with the degree symbol °, and write it as sin 720°.
If you have been looking for what is sin 720°, or if you have been wondering about sin 720 degrees in radians, then you are right here, too.
In this post you can find the sin 720° value, along with identities.
Read on to learn all about the sin of 720°.
Sin 720 Degrees
If you want to know what is sin 720 degrees in terms of trigonometry, then navigate straight to the explanations in the next paragraph; what’s ahead in this section is the value of sin 720°:
sin 720° = 0
sin 720 degrees = 0
The sin of 720 degrees is 0, the same as sin of 720 degrees in radians. To obtain 720 degrees in radian multiply 720° by $\pi$ / 180° = 4/1 $\pi$. Sin 720degrees = sin (4/1 × $\pi)$.
Our results of sin720° have been rounded to five decimal places. If you want sine 720° with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate sin 720 degrees insert the angle 720 in the field labelled °, but if you want to calculate sin 720 in radians, then you have to press the swap unit button first.
Calculate sin [degrees]
The identities of sine 720° are as follows:
= cos (90°-720°) = cos -630°
= sin (180°-720°) = sin -540°
-sin720°
= cos (90°+720°) = cos 810°
= sin (180°+720°) = sin 900°
There are more formulas for the double angle (2 × 720°), half angle ((720/2)°) as well as the sum, difference and products of two angles such as 720° and β.
You can locate all of them in the respective article found in the header menu. To find everything about sin -720° click the link. And here is all about cos 720°, including, for instance, a converter.
In terms of the other five trigonometric functions, sin of 720° =
- $\pm \sqrt{1-\cos^{2} 720 ^\circ}$
- $\pm\frac{\tan 720^\circ}{\sqrt{1 + \tan^{2} 720^\circ}}$
- $\pm\frac{1}{\sqrt{1 + \cot^{2} 720^\circ}}$
- $\pm\frac{\sqrt{\sec^{2} 720^\circ – 1} }{\sec 720^\circ}$
- $\frac{1}{\csc 720^\circ}$
As the cosecant function is the reciprocal of the sine function, 1 / csc 720° = sin720°.
In the next part of this article of this article we discuss the trigonometric significance of sin720°, and there you can also learn what the search calculations form in the sidebar is used for.
What is sin 720°?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, 720 degrees is the angle formed by the two sides x and r; r moving counterclockwise is the positive angle.
As detailed in the unit-circle definition on our homepage, assumed r = 1, in the intersection of the point (x,y) and the circle, y = sin 720°.
Note that you can locate many terms including the sine720° value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of sin720°.
Along the same lines, using the aforementioned form, can you look up terms such as sin 720° value, sin 720, sin720° value and what is the sin of 720 degrees, just to name a few.
Given the periodic property of sine of 720°, to determine the sine of an angle > 360°, e.g. 1440°, calculate sin 1440° as sin (1440 Mod 360)° = sine of 720°, or look it up with our form.
