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 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.
What is this expression as the cosine of an angle cos30cos55 plus sin30sin55?
cos(30)cos(55)+sin(30)sin(55)=cos(30-55) = cos(-25)=cos(25) Note: cos(a)=cos(-a) for any angle 'a'. cos(a)cos(b)+sin(a)sin(b)=cos(a-b) for any 'a' and 'b'.
How do you find cos 60?
cos(60) = 0.5 The simplest way is to use a calculator.
How do you put sec in a TI 84 calculator?
For any calculator Sec(Secant) = 1/Cos Csc (Cosecant) = 1/ Sin Cot (Cotangent) = 1/Tan
What button on the graphing calculator is arc cos?
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.

How do you enter cosign on a scientific calculator?
Press the button labeled "COS"
Where is arcosine on a TI-84 calculator?
It is labeled as "cos-1" on the calculator. But arcosine and inverse cosine are just two names for the same thing.
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.
Find the value of y if sin y equals cos 48?
y = arcsin( cos 48 ); arcsin may be seen as sin-1 on your calculator.
What is the inverse cosine of negative one?
the answer is 180 degrees; since cos 180⁰ = -1, then cos-1 -1 = 180⁰ mathematically cos-1-1 here calculator is required and you'll get answer 180 degrees.....
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] [±] [=]
How do you solve the equation negative 3 cos t equals 1 in the interval from 0 to 2 pi?
Isolate cos (t): cos(t)=1/3. Use a calculator from here because the answer is not an integer or a simple number.
