For the cosine of 3pi/4 we usage the abbreviation cos because that the trigonometric duty and write it as cos 3pi/4.

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

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

In this post you can uncover the cos 3pi/4 value, along with identities.

Read ~ above to discover all around the cos that 3pi/4.

Cos 3Pi/4 Radians

If you want to understand what is cos 3pi/4 radians in terms of trigonometry, climate navigate directly to the explanations in the next paragraph; what’s front 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-ccbdc80e3f3f9426effa668a-="">Share on Facebook

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

Our outcomes of cos3pi/4 have actually been rounded to 5 decimal places. If you want cosine 3pi/4 with higher accuracy, then use the calculator below; ours tool displays ten decimal places.

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

The identities of cosine 3pi/4 room as follows:cos3pi/4= sin (pi/2 + 3pi/4) = sin 5/4 pi= sin (pi/2 – 3pi/4) = sin -1/4 pi

-cos3pi/4= cos (pi + 3pi/4) = cos 7/4 pi= cos (pi – 3pi/4) = cos 1/4 piNote the cos3pi/4 is periodic: cos (3pi/4 + n × 2pi) = cos 3pi/4, n$hspace5px in hspace5px mathbbZ$.

There are more formulas because that the dual angle (2 × 3pi/4), half angle ((3pi/4/2)) and also the sum, difference and products of two angles such together 3pi/4 and β.

You have the right to locate all of them in the respective write-up found in the header menu. To uncover everything about cos -3pi/4 click the link. And here is all about sin 3pi/4, including, because that instance, a converter.

In terms of the other five trigonometric functions, cos of 3pi/4 =

$pm sqrt1-sin^2 3pi/4 $ $pmfrac1sqrt1 + an^2 3pi/4$ $pmfraccot 3pi/4sqrt1 + cot^2 3pi/4$ $frac1sec 3pi/4$ $pmfracsqrtcsc^2 (3pi/4) – 1 csc 3pi/4$

As the cosine function is the mutual of the secant function, 1 / sec 3pi/4 = cos3pi/4.

In the next part we talk about the trigonometric definition of cos3pi/4, and there girlfriend can likewise learn what the search calculations kind in the sidebar is supplied for.

What is cos 3Pi/4?

In a circle with the radius r, the horizontal axis x, and also the vertical axis y, 3pi/4 is the angle created by the two sides x and r; r relocating counterclockwise is the positive angle.

As comprehensive in the unit-circle definition on our homepage, assumed r = 1, in the intersection that the allude (x,y) and also the circle, x = cos 3pi/4.

Note that you can locate many terms including the cosine3pi/4 value utilizing the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of cos3pi/4.

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

Given the regular property of cosine of 3pi/4, to identify the cosine the an edge > 2pi, e.g. 19/4 pi, calculation cos 19/4 pi together cos (19/4 pi mode 2pi) = cosine the 3pi/4, or look the up with our form.


The typically asked inquiries in the context encompass what is cos 3pi/4 radians and also what is the cos the 3pi/4 degrees for example; analysis our content they room no-brainers.

But, if over there is other else around cosine 3pi/4 you would favor to know, fill in the form on the bottom the this post, or send us an e-mail with a topic line such as cosine 3pi/4 radians.
