First make sure the calculator is in 'Degree Mode'.
Then press 'Cos' , followed by the angle in degrees, say '60' degrees, then press equals (=), and the answer should read '0.5'.
NB If the calculator is in 'Radiuan Mode'
Press 'Cos' followed by ' pi' divide '3' . Then equals (=) , again the answer should be '0.5'.
What else can I help you with?
How do you get cosine of 70 degrees?
Note: When doing trigonometry, it is highly recommeded that you have a scientific calculator at hand. Also, make sure your calculator is in Degree (D or Deg) mode and not Radian (R or Rad). To find the cosine of 70o, press 'cos', then type in 70, then press equals. You should get 0.342 (to the nearest 3 decimal places).
How do you find an angle using sine cosine tangent?
First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
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.
What is cos on a calculator mean?
Cos is short for Cosine ( Complementary Sine) Similrly Sin is short for Sine Tan is short for Tangent.
How do you calculate sin20?

How do you acquire secant in scientific calculator?
You can calculate the cosine and then its reciprocal.
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.

Short for cosine. Check this site out for detailed info. http://www.clarku.edu/~djoyce/trig/
What does tangent on a scientific calculator mean?
It is a trigonometric function, equivalent to the sine of an angle divided by the cosine of the same angle.
What is the cosine formula in trig?
so what you do is Soh Cah Toa, Cah for cosine so if you have a triangle you do the length of the adjacent divided by hypotenuse and the number you get (the rest depends on the calculator) you press 2nd or shift then cos button on your calculator. remember the calculator must be scientific the actual formula is cosine theta=a h then you write the numbers in and you should know the rest
How do you find the cosin of a right triangle?
put in cosine in your calculator and then take the cosine of the length of the adjacent length over the length of the hypotenuses length

How do you find modulus of number in scientific calculator?
The way you find modulus of a number on a scientific calculator depends on the model of calculator. On the TI-86, you use mod (x,y) or x mod y to find modulus.
How do you find the cosine of 35?
If you have a suitable calculator, you can find it directly. It is also the same as the sine of 55 degrees, which can be looked up in many tables.
How do you solve cosine 140?
Well, the usual way would be to use a scientific calculator - one that has support for trigonometric functions such as cosine. Make sure the calculator is set to "degrees", since I assume the "140" represents degrees. Of course you might also use the infinite series for the cosine function (which is basically what the calculator does). Convert the angle to radians, then use the infinite Tailor series: cos x = 1 - x2/2! + x4/4! - x6/6! + ...
