For the arctangent press INV then TAN. The INV key is two up and one left of the "7" key.

### Arctan

Press SHIFT then tan. The shifted function of the tan key is marked tan^-1 for inverse tangent, another name for the arctangent.

### How to use calculator on how to evaluate trigonometric functions

The FX-115ES is somewhat different to other calculators you might know. The sequence of keys is more like writing up a calculation in a textbook, whereas for "normal" calculators operations are reversed in some places.
For example, with most calculators you would type 30 [sin] to calculate the sine function of 30 degrees, with the 115ES its [sin] 30 [=].

The 115ES has all the standard trigonometric functions:
• Standard functions (sin, cos, tan), type the [sin], [cos] or [tan] key followed by the argument.
• Inverse trigonometric (sin?Â¹, cos?Â¹, tan?Â¹), type [SHIFT][sin], [SHIFT][cos] or [SHIFT][tan] followed by the argument.
• Hyperbolic functions (sinh, cosh, tanh), type [HYP][sin], [HYP][cos], or [HYP][tan] followed by the argument.
• and finally inverse hyperbolic (sinh?Â¹, cosh?Â¹, tanh?Â¹), its [SHIFT][HYP][sin], [SHIFT][HYP][cos], or [SHIFT][HYP][tan] followed by the argument.
Arguments can be given as numbers with mantissa (2.718), as fractions (use the fraction key below [CALC]) or as degree, minute, second (30Â°12'45") using the [Â°'"] key for input. To switch between degrees (1 circle = 360Â°), radians (1 circle = 2?), or grad (1 circle = 400 gon), use [SHIFT][DRG>].

### 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.

### How can i get the shift of sine, cosine, and tangent in my calculator?

I am not sure what you mean, because your question already shows what you have to do.
To use the functions marked on the body of the calculator you use either the SHIFT key for the ALPHA key.
If a key has next to it (on the body of the calculator) two markings, the one on the left is accessed with SHIFT, and the one on the right with ALPHA. Colors of commands on calculator body are coordinated with the colors of the Shift key and the ALPHA key.

The question I am asking is whether you know what [SHIFT][COS] means. You probably do, but just in case you do not (no reflexion on your abilities)
[SHIFT] [COS] gives access to the arc cosine function, [SHIFT][SIN] the arc sine function, and [SHIFT][TAN] the arctangent.

### How to do inverse of tan cos sin

The inverse trigonometric function share each the same physical key with its direct function. The inverse trigonometric functions are accessed with the [SHIFT] key
[SHIFT] [SIN] accesses the arcsine
[SHIFT][COS] accesses the arccosine
and [SHIFT][TAN] the arctangent.

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

Hello,

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.

### I need to know how to put in the info for tan^(-1)(whatever)=

Press SHIFT [ATAN] whatever ENTER

ATAN stands for arctangent (inverse tangent, tan^(-1)) and is the shifted function of the tangent key.
