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 is the Cosine of 62 degrees?
The cosine of 62 degrees is approximately 0.4695. This value can be found using a scientific calculator or trigonometric tables. Cosine values represent the ratio of the adjacent side to the hypotenuse in a right triangle for the given angle.
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 solve COS?
To solve for the cosine (COS) of an angle, you can use the unit circle, where the cosine of an angle corresponds to the x-coordinate of the point on the circle at that angle. Alternatively, you can use trigonometric identities or the cosine function on a scientific calculator by inputting the angle in degrees or radians. For specific problem solving, using the cosine rule in triangles may also be applicable to find unknown sides or angles.
What is the value of the cosine of 55 degrees?
The value of the cosine of 55 degrees is approximately 0.5736. This value can be found using a scientific calculator or trigonometric tables. Cosine values are used in various applications, including physics and engineering, to analyze angles and distances.
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).
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.
What is cos on a scientific calculator?
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
What is the Cosine of 62 degrees?
The cosine of 62 degrees is approximately 0.4695. This value can be found using a scientific calculator or trigonometric tables. Cosine values represent the ratio of the adjacent side to the hypotenuse in a right triangle for the given angle.
How do you get cosine of 70 degrees?

What does cosine mean on a calculator?
The same thing that cosine means in trigonometry, a calculator just allows you to calculate such functions quickly.
Where can one find a free online scientific calculator?
One can find free online scientific from websites like Web2, Online-Calculator, Meta-Calculator, Calculator-Tab, MathOpenRef and Alcula. One can also find scientific calculator software pre-installed in Windows.
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.
