Welcome to cos 709°, our post aboutthe cosine of 709 degrees.
For the cosine of 709 degrees we use the abbreviation cos for the trigonometric function together with the degree symbol °, and write it as cos 709°.
If you have been looking for what is cos 709°, or if you have been wondering about cos 709 degrees in radians, then you are right here, too.
In this post you can find the cos 709° value, along with identities.
Read on to learn all about the cos of 709°.
Cos 709 Degrees
If you want to know what is cos 709 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 709°:
cos 709° = 0.98163
cos 709 degrees = 0.98163
The cos of 709 degrees is 0.98163, the same as cos of 709 degrees in radians. To obtain 709 degrees in radian multiply 709° by $\pi$ / 180° = 709/180 $\pi$. Cos 709degrees = cos (709/180 × $\pi)$.
Our results of cos709° have been rounded to five decimal places. If you want cosine 709° with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate cos 709 degrees insert the angle 709 in the field labelled °, but if you want to calculate cos 709 in radians, then you have to press the swap unit button first.
Calculate cos [degrees]
The identities of cosine 709° are as follows:
= sin (90°+709°) = sin 799°
= sin (90°-709°) = sin -619°
-cos709°
= cos (180°+709°) = cos 889°
= cos (180°-709°) = cos -529°
There are more formulas for the double angle (2 × 709°), half angle ((709/2)°) as well as the sum, difference and products of two angles such as 709° and β.

In terms of the other five trigonometric functions, cos of 709° =
- $\pm \sqrt{1-\sin^{2} 709 ^\circ}$
- $\pm\frac{1}{\sqrt{1 + \tan^{2} 709^\circ}}$
- $\pm\frac{\cot 709^\circ}{\sqrt{1 + \cot^{2} 709^\circ}}$
- $\frac{1}{\sec 709^\circ}$
- $\pm\frac{\sqrt{\csc^{2} 709^\circ – 1} }{\csc 709^\circ}$
As the cosine function is the reciprocal of the secant function, 1 / sec 709° = cos709°.

What is cos 709°?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, 709 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 709°.
Note that you can locate many terms including the cosine709° value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos709°.
Along the same lines, using the aforementioned form, can you look up terms such as cos 709° value, cos 709, cos709° value and what is the cos of 709 degrees, just to name a few.
Given the periodic property of cosine of 709°, to determine the cosine of an angle > 360°, e.g. 1429°, calculate cos 1429° as cos (1429 Mod 360)° = cosine of 709°, or look it up with our form.
