Press the MODE key a certain number of times until you reach the screen that says DEG RAD, GRA. Press the number that corresponds to DEG.

Sin cos tan


To use these functions press the sin, cos, or tan button followed by the angle you are looking for the value for if in degree mode or the radian value your are looking for if in radian mode.

I'm just beginning to learn about trigonometric functions (sin, cosine & tangent). My math book says for a problem such as "4 cos 75.8", I should press 4, x, 75.8, cos, = (in that order)....


Try 4 x cos 7 5 . 8 =

The fx-300MS is a more advanced calculator than what the book is describing. It evaluates cosine(x) as cos x rather than x, cos.

How to solve for the trigonometric functions in the casio scientific calculator?


Press the relevant function key [SIN],[COS],[TAN] followed by the angle value.
For inverse trigonometric functions [SIN^-1], COS^-1], or [TAN^-1], Press [SHIFT][SIN], [SHIFT][COS], or [SHIFT][TAN].
For other functions
sec(x)=1/cos(x)
csc(x)=1/sin(x)
cot(x)=1/tan(x)

When calculating trigonometric functions one must make sure that the angle unit the calculator is using is the correct one.

Changing the mode in a casio


Hi,
To change the default angle unit, you press the [MODE] button a certain number of times until display shows a rectangle inside which Deg Rad Grad appear on the top line and 1 2 3 on bottom line, with 1 under Deg, 2 under Rad, and 3 under Grad.
Press the number key corresponding to your case, 1. All angle values you feed the trigonometric functions will be considered to be in degrees. If you use the inverse trigonometric functions to find angles, the results will be in degrees.

Hope it helps.

How to use the cosine,tangent etc functions of calculator fx-82ES plus


Hello,
1.Set the correct angle unit required by your problem: degrees, radians, or grads. [SHIFT][MODE] [3:deg] or [4:Rad]

2. Press the key for the function COS, SIN, or TAN
[COS] displays Cos(

3.Enter the angle 12 deg Screen shows cos(12
Close the right parenthesis ) Screen shows cos(12)
4.Press [=] Screen displays 0.9781

If you want the inverse trigonometric functions you access them with arccos [SHIFT] [COS] (cos^-1)
arcsin [SHIFT][SIN] (sin^-1)
actan [SHIFT][TAN] (tan^-1)

You have to know the principal domain for the inverse trigonometric functions (see any book on trigonometry) to understand the results.
Hope it helps.

How to use trig function keys on my casio fx-300ES


Hello,
You have 3 keys for the main trigonometric functions: [SIN], [COS] and [TAN]
To use them correctly you must set the angle unit to the one your problem calls for.
Press [SIFT][MODE] [3:Deg] for degree, [4:Rad] for radian, [5:Grad] for grad. Dependig on angle unit chosen a small D, R, or G appears on the top of the screen.

If you need the inverse trigonometric functions arcsine, arccosine, arctangent, you access them by first pressing the [SHIFT] key
Thus
arcsine [SHIFT][SIN] (sin^-1)
arcosine [SHIFT][COS] (cos^-1)
arctangent [SHIFT][TAN] (tan^-1)

The syntax for the function is
[SIN] # [ ) ] [=]; [SIN] 30 [ ) ] [=] gives 0.5
[COS] # [ ) ] [=] [COS] 19 [ ) ] [=] gives 0.945518576

Note: if the argument of the functions are numbers, the right parenthesis is not necessary. But if the argument is an expression (with various operations) better put the parenthesis to make sure the calculator is performing as one wants it to.

By the way, there are no keys, or key combinations to calculate cotangent, cosecant, and secant, but you can use the definitions:

cotangent (x) = 1/tan(x) Do not confuse it with tan^-1
cosecant(x) = 1/sin(x) Do not confuse it with sin^-1
secant(x) = 1/cos(x) Do not confuse it with cos^-1

Hope it helps.
