Welcome to cos 197°, our post aboutthe cosine of 197 degrees.
For the cosine of 197 degrees we use the abbreviation cos for the trigonometric function together with the degree symbol °, and write it as cos 197°.
If you have been looking for what is cos 197°, or if you have been wondering about cos 197 degrees in radians, then you are right here, too.
In this post you can find the cos 197° value, along with identities.
Read on to learn all about the cos of 197°.
Cos 197 Degrees
If you want to know what is cos 197 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 cos 197°:
cos 197° = -0.9563
cos 197 degrees = -0.9563
The cos of 197 degrees is -0.9563, the same as cos of 197 degrees in radians. To obtain 197 degrees in radian multiply 197° by $\pi$ / 180° = 197/180 $\pi$. Cos 197degrees = cos (197/180 × $\pi)$.
Our results of cos197° have been rounded to five decimal places. If you want cosine 197° with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate cos 197 degrees insert the angle 197 in the field labelled °, but if you want to calculate cos 197 in radians, then you have to press the swap unit button first.
Calculate cos [degrees]
The identities of cosine 197° are as follows:
= sin (90°+197°) = sin 287°
= sin (90°-197°) = sin -107°
-cos197°
= cos (180°+197°) = cos 377°
= cos (180°-197°) = cos -17°
There are more formulas for the double angle (2 × 197°), half angle ((197/2)°) as well as the sum, difference and products of two angles such as 197° and β.

In terms of the other five trigonometric functions, cos of 197° =
- $\pm \sqrt{1-\sin^{2} 197 ^\circ}$
- $\pm\frac{1}{\sqrt{1 + \tan^{2} 197^\circ}}$
- $\pm\frac{\cot 197^\circ}{\sqrt{1 + \cot^{2} 197^\circ}}$
- $\frac{1}{\sec 197^\circ}$
- $\pm\frac{\sqrt{\csc^{2} 197^\circ – 1} }{\csc 197^\circ}$
As the cosine function is the reciprocal of the secant function, 1 / sec 197° = cos197°.
In the next part we discuss the trigonometric significance of cos197°, and there you can also learn what the search calculations form in the sidebar is used for.
What is cos 197°?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, 197 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, x = cos 197°.
Note that you can locate many terms including the cosine197° value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos197°.
Along the same lines, using the aforementioned form, can you look up terms such as cos 197° value, cos 197, cos197° value and what is the cos of 197 degrees, just to name a few.
Given the periodic property of cosine of 197°, to determine the cosine of an angle > 360°, e.g. 917°, calculate cos 917° as cos (917 Mod 360)° = cosine of 197°, or look it up with our form.
