For the cosine that 3pi/4 we usage the abbreviation *cos* because that the trigonometric function and compose it together cos 3pi/4.

You are watching: Cos(-3pi/4)

If you have been trying to find *what is cos 3pi/4*, or if you have actually been wondering around cos 3pi/4 radians in degrees, then you are right here, too.

In this short article you can find the cos 3pi/4 value, in addition to identities.

Read top top to learn all about the cos of 3pi/4.

## Cos 3Pi/4 Radians

If you want to recognize *what is cos 3pi/4 radians* in regards to trigonometry, then navigate directly to the explanations in the next paragraph; what’s ahead in this section is the worth of cos 3pi/4:

cos3pi/4 = -√(2)/2cos 3pi/4 = -√(2)/2cos 3pi/4 radians = -√(2)/2" onclick="if (!window.__cfRLUnblockHandlers) return false; return fbs_click()" target="_blank" rel="nofollow noopener noreferrer" data-cf-modified-e5c16977016e52069eed7bc9-="">

The cos the 3pi/4 radians is -√(2)/2, the same as cos of 3pi/4 radians in degrees. To adjust 3pi/4 radians to degrees multiply 3pi/4 through by 180° / $pi$ = 135°. Cos 3pi/4 = cos 135 degrees.

Our results of cos3pi/4 have actually been rounded to five decimal places. If you want cosine 3pi/4 with higher accuracy, then use the calculator below; our tool display screens ten decimal places.

To calculate cos 3pi/4 radians insert the edge 3pi/4 in decimal notation, however if you desire to calculation cos 3pi/4 in degrees, climate you have to press the swap unit button first.

## What is cos 3Pi/4?

In a circle through the radius r, the horizontal axis x, and the upright axis y, 3pi/4 is the angle formed by the 2 sides x and also r; r moving counterclockwise is the confident angle.

As detailed in the unit-circle meaning on our homepage, presume r = 1, in the intersection the the allude (x,y) and also the circle, x = cos 3pi/4.

Note the you deserve to locate numerous terms consisting of the cosine3pi/4 value utilizing the search form. On mobile tools you can discover it through scrolling down. Enter, because that instance, value of cos3pi/4.

Along the very same lines, utilizing the previously mentioned form, deserve to you look up state such together cos 3pi/4 value, cos 3pi/4, cos3pi/4 value and *what is the cos that 3pi/4 radians*, just to name a few.

Given the periodic property the cosine the 3pi/4, to recognize the cosine that an angle > 2pi, e.g. 19/4 pi, calculation cos 19/4 pi together cos (19/4 pi mode 2pi) = cosine the 3pi/4, or look it up with our form.

## Conclusion

The generally asked concerns in the context encompass *what is cos 3pi/4 radians* and *what is the cos the 3pi/4 degrees* because that example; analysis our content they space no-brainers.

But, if over there is miscellaneous else around cosine 3pi/4 girlfriend would like to know, fill in the type on the bottom of this post, or send us an email with a topic line such together cosine 3pi/4 radians.
