What kind of calculator do I need for my Trigonometry class?
You should get the HP 33S Scientific Calculator because it has 32KB of memory, keystroke programming, linear regression, binary calculation and conversion, trigonometric, inverse-trigonometric and hyperbolic functions
How will you simplify algebraic expressions?
use a calculator
What does sin stand for on a calulator?
The "sin" button on a calculator gives the sine trigonometric ratio of the given angle.
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.
How do you find trigonometric ratios without a calculator?
There are a few ways. First, there are a multitude of trigonometric tables which list the sines and cosines of a variety of values. if you now one trigonometric value of a number, you can find all the others by hand, and you can also use a Taylor series approximation to find a fairly accurate value. (In fact, many calculators use Taylor series to find trigonometric values.)
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.
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.
What is tan on a scientific calculator?
It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle
How does a scientific calculator compute the value of sin 41.5 degrees?
Trigonometric functions are calculated using a polynomial approximation. The exact polynomial used may be different on different calculators.
How do you make trigonometric calculator in c plus plus?
include file math.h and you get most C++ functions for trigonometry, for instance,sin(), cos(), tan(), asin(), acos(), and atan() etc.
How do you perform sine?
You hit the SIN key on the calculator. ^_^ Really though, that's just about the only way, unless you have an old-fashioned trigonometric table with sines and haversines all over it.
Why the calculator gave value -22.62 degree instead of directly giving value 337.38 degree?
Because of the periodicity of trigonometric functions, calculators will only give the principal value. It would appear that the principal range for your calculator is 180 to 180 degrees rather than 0 to 360.
