Welcome to sin 211°, our post aboutthe sine of 211 degrees.
For the sine of 211 degrees we use the abbreviation sin for the trigonometric function together with the degree symbol °, and write it as sin 211°.
If you have been looking for what is sin 211°, or if you have been wondering about sin 211 degrees in radians, then you are right here, too.
In this post you can find the sin 211° value, along with identities.
Read on to learn all about the sin of 211°.
Sin 211 Degrees
If you want to know what is sin 211 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 211°:
sin 211° = -0.51504
sin 211 degrees = -0.51504
The sin of 211 degrees is -0.51504, the same as sin of 211 degrees in radians. To obtain 211 degrees in radian multiply 211° by $\pi$ / 180° = 211/180 $\pi$. Sin 211degrees = sin (211/180 × $\pi)$.
Our results of sin211° have been rounded to five decimal places. If you want sine 211° with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate sin 211 degrees insert the angle 211 in the field labelled °, but if you want to calculate sin 211 in radians, then you have to press the swap unit button first.
Calculate sin [degrees]
The identities of sine 211° are as follows:
= cos (90°-211°) = cos -121°
= sin (180°-211°) = sin -31°
-sin211°
= cos (90°+211°) = cos 301°
= sin (180°+211°) = sin 391°
There are more formulas for the double angle (2 × 211°), half angle ((211/2)°) as well as the sum, difference and products of two angles such as 211° and β.
You can locate all of them in the respective article found in the header menu. To find everything about sin -211° click the link. And here is all about cos 211°, including, for instance, a converter.
In terms of the other five trigonometric functions, sin of 211° =
- $\pm \sqrt{1-\cos^{2} 211 ^\circ}$
- $\pm\frac{\tan 211^\circ}{\sqrt{1 + \tan^{2} 211^\circ}}$
- $\pm\frac{1}{\sqrt{1 + \cot^{2} 211^\circ}}$
- $\pm\frac{\sqrt{\sec^{2} 211^\circ – 1} }{\sec 211^\circ}$
- $\frac{1}{\csc 211^\circ}$
As the cosecant function is the reciprocal of the sine function, 1 / csc 211° = sin211°.
In the next part of this article of this article we discuss the trigonometric significance of sin211°, and there you can also learn what the search calculations form in the sidebar is used for.
What is sin 211°?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, 211 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 211°.
Note that you can locate many terms including the sine211° value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of sin211°.
Along the same lines, using the aforementioned form, can you look up terms such as sin 211° value, sin 211, sin211° value and what is the sin of 211 degrees, just to name a few.
Given the periodic property of sine of 211°, to determine the sine of an angle > 360°, e.g. 931°, calculate sin 931° as sin (931 Mod 360)° = sine of 211°, or look it up with our form.
