If you are using the US character layout, it should be SHIFT-2. That is, hold down SHIFT and press the number 2.

Good luck. Please let us know if this solves your problem.

Set the angle unit to degrees.

Try sin (30)=, and 30 sin

**The correct answer is 0.5**

Usually if pressing the sin key display**sin(** then you should use **sin(angle) =**.

Try sin (30)=, and 30 sin

Depending on calculator, enter angle then press sin key or press sin key then enter angle and press equal sign. Make sure angle units are the ones you want (degrees, radians or gradians.

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:

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?¹, cos?¹, tan?¹), 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?¹, cosh?¹, tanh?¹), its [SHIFT][HYP][sin], [SHIFT][HYP][cos], or [SHIFT][HYP][tan] followed by the argument.

For writing sine 52 degrees 17 minutes.

1.press sin key.

2.Enter 52 press the key which is above ENG key which look likes 3 commas.

3.Now enter 17 and press the degrees and minute key above the ENG key.

4.After that press '=' key.You will get the answer as .7910.

Thank you.

You would press on the SIN key, "sin(" should come on the display, then enter the value, for example 3.5 or -1 so that the display shows

sin(3,5) or sin(-1) for example.

remember to close the sin with the ) on the end.

**sin(-1) = -0.841470985**

sin(3,5) or sin(-1) for example.

remember to close the sin with the ) on the end.

The cosecant function does not have a specific key on any calculator because it can be easily calculated as the reciprocal of sine.

Thus csc(-330°)=1/sin(-330°)=2

sin(-330°)=sin(360°-330°)=sin(30°)=0.5

csc(-330°)=1/0.5=2

If you do not want to be bothered with these facts, just calculate the sine of -330° and take the reciprocal of the result using the [x^-1] key. For the minus sign before 330, use the change sign key (-). Close the right parenthesis.

[SIN] [(-)] 330 [)] [x^-1]

Thus csc(-330°)=1/sin(-330°)=2

sin(-330°)=sin(360°-330°)=sin(30°)=0.5

csc(-330°)=1/0.5=2

If you do not want to be bothered with these facts, just calculate the sine of -330° and take the reciprocal of the result using the [x^-1] key. For the minus sign before 330, use the change sign key (-). Close the right parenthesis.

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.

You have the calculator set up to do radians instead of degrees. I'm not that familiar with the TI-83 but I believe you should look for a key labeled DRG. This stands for Degrees, Radians, and, Grads. Push this key and then use the arrow keys to move from RAD to DEG and hit enter. Now enter Sin(30) and you should get 0.5.
