Welcome to sin 557°, our post aboutthe sine of 557 degrees.
For the sine of 557 degrees we use the abbreviation sin for the trigonometric function together with the degree symbol °, and write it as sin 557°.
If you have been looking for what is sin 557°, or if you have been wondering about sin 557 degrees in radians, then you are right here, too.
In this post you can find the sin 557° value, along with identities.
Read on to learn all about the sin of 557°.
Sin 557 Degrees
If you want to know what is sin 557 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 557°:
sin 557° = -0.29237
sin 557 degrees = -0.29237
The sin of 557 degrees is -0.29237, the same as sin of 557 degrees in radians. To obtain 557 degrees in radian multiply 557° by $\pi$ / 180° = 557/180 $\pi$. Sin 557degrees = sin (557/180 × $\pi)$.
Our results of sin557° have been rounded to five decimal places. If you want sine 557° with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate sin 557 degrees insert the angle 557 in the field labelled °, but if you want to calculate sin 557 in radians, then you have to press the swap unit button first.
Calculate sin [degrees]
The identities of sine 557° are as follows:
= cos (90°-557°) = cos -467°
= sin (180°-557°) = sin -377°
-sin557°
= cos (90°+557°) = cos 647°
= sin (180°+557°) = sin 737°
There are more formulas for the double angle (2 × 557°), half angle ((557/2)°) as well as the sum, difference and products of two angles such as 557° and β.
You can locate all of them in the respective article found in the header menu. To find everything about sin -557° click the link. And here is all about cos 557°, including, for instance, a converter.
In terms of the other five trigonometric functions, sin of 557° =
- $\pm \sqrt{1-\cos^{2} 557 ^\circ}$
- $\pm\frac{\tan 557^\circ}{\sqrt{1 + \tan^{2} 557^\circ}}$
- $\pm\frac{1}{\sqrt{1 + \cot^{2} 557^\circ}}$
- $\pm\frac{\sqrt{\sec^{2} 557^\circ – 1} }{\sec 557^\circ}$
- $\frac{1}{\csc 557^\circ}$
As the cosecant function is the reciprocal of the sine function, 1 / csc 557° = sin557°.
In the next part of this article of this article we discuss the trigonometric significance of sin557°, and there you can also learn what the search calculations form in the sidebar is used for.
What is sin 557°?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, 557 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 557°.
Note that you can locate many terms including the sine557° value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of sin557°.
Along the same lines, using the aforementioned form, can you look up terms such as sin 557° value, sin 557, sin557° value and what is the sin of 557 degrees, just to name a few.
Given the periodic property of sine of 557°, to determine the sine of an angle > 360°, e.g. 1277°, calculate sin 1277° as sin (1277 Mod 360)° = sine of 557°, or look it up with our form.
