It is usually [Shift] [cos]
though on some calculators it may be [2ndF] [cos]
The arc cos function is often written as cos-1 or acos, and on most calculators is written above the button to press; the colour of the text used to write it usually matches up with the key needed to press before the cos button.
On Casio calculators, it is [shift][cos] with the shift key labelled in yellow, and cos-1 written in yellow.
On a Texas Instruments calculator it is [2nd] [cos] with the 2nd key labelled in blue and the cos-1 written in blue.
On a Hewlett Packard calculator it is [<up_arrow_pointing_left>][cos] with the up_arrow_pointing left a white key with a black arrow and ACOS written in white above the cos button.

∙ 14y agoWe don't know what style, brand, or model of calculator you have, so we can only speculate
and hope we get lucky. Here are two suggestions that may help:
1). In order to save space on the buttons and around them,
"arc cos" is often written as "cos-1". Look for that symbol.
2). If you obtained the calculator recently, you may have also received a
small booklet with it. In that booklet are all kinds of helpful instructions,
not only for replacing the batteries in the calculator, and getting it fixed
when it dies, but also step-by-step instructions on how to do stuff with it.

How do you put sec in a TI 84 calculator?
sec = 1 / cos sec = 1 / cos
What dies COS stand for on calculator?
"COS" stands for "Cosine", which is one of the 6 trigonometric functions. Similarly, "SIN" stands for Sine, and TAN stands for Tangent.
How do you put sec cubed in a calculator?
sec x = 1/cos x → sec³ x = 1/cos³ x or sec³ x = (cos x)^-3 Therefore to enter sec³ x on a calculator: Newer, "natural" calculators: mathio: sec³ x → [x-power] [cos] [<angle>] [)] [navigate →] [(-)] [3] [=] lineio: sec³ x → [(] [cos] [)] [)] [x-power] [(-)] [3] [)] [=] Older, function acts on displayed number calculators: sec³ x → [angle] [cos] [x-power] [3] [±] [=]
What is The value of arccos (-0.32) as a decimal to the nearest hundredth of a degree in the box.?
arc cos -0.32 is approx: --------------- | 108.66° | ---------------
Is cos squared x the same as cos x squared?
No. Cos squared x is not the same as cos x squared. Cos squared x means cos (x) times cos (x) Cos x squared means cos (x squared)
What is cosine of 23 degree angle?
This can be done on a graphing calculator by making sure you have your calculator in degrees mode, and then tentering the cos(23). You get an answer of 0.9205048535.
How can you get a sine cosine or tangent on a graphing calculator?
If you mean you want to make a graph of one of those functions, hit the (y=) (just under the screen of the calculator) button so you can create a graph, then hit the (sin) (cos) (tan) (right above the number pad) button you want to make a graph of, then the (X,T,O,n) (right next to the (ALPHA) button to the left) button and hit (graph) (also right under the screen of the calculator). All locations of buttons are based on TI-83 and TI-84 graphing calculator models.
How do you enter cosign on a scientific calculator?
Press the button labeled "COS"
What is a good calculator for trigonometry?
Any calculator sold as a "scientific calculator" has the basic trigonometric functions (sin, cos, tan) and the inverse trigonometric functions (arc-sin, arc-cos, arc-tan). That's about all you need.You can also use the calculator that comes on your computer - for example, in Windows, press Windows-R, and then type "calc". You may have to change the calculator mode, to "scientific calculator". Yet another option is a spreadsheet, for example, Excel. Note that in Excel, angles are expressed in radians; if you want degrees, you also need the special functions to convert degrees to radians, or radians to degrees. However, if you want to do your homework while you are NOT at your computer, you are better off buying a calculator.
How do you find cos 60?
cos(60) = 0.5 The simplest way is to use a calculator.
How do you find the angle of a cosine?
You mean, you have the cosine, and want the angle? That is called arc-cosine, often written as cos-1x. Your scientific calculator should have a "shift" key or something similar, which you press, followed by the cosine key. That will give you the inverse cosine or arc-cosine.
How do you find cosine on a scientific calculator?
Look for a button marked "cos". Note that some calculators have degrees, radians and other measurements. So check you are in the right mode.
How do you put sec in a TI 84 calculator?
sec = 1 / cos sec = 1 / cos
What is the unit of the angle subtend by an arc are?
cos liverpool are the best team in the world
The graph of y equals arc cos 2x?
This site is not suitable for graphs.
How do you make 'cot' and 'csc' on a TI-84 graphing calculator?
From math class, some trigonometric identities: cot x = 1/tan x csc x = 1/sin x sec x = 1/cos x There are no built-in cot or csc formulas, so use the above. Remember that these give errors when tan x, sin x, or cos x are equal to 0.
Where is cos2 on a ti-83 plus calculator?
There is not cos2 button on a TI-83 plus. You will need to enter the cosine function and then square it. (Press the x2 button to get the squared function.) To type cos2(90) on a TI-83 plus, for example, type: cos(90)2
