Question about Casio FX-115ES Scientific Calculator

Ad

The key is called SHIFT on Casio calculators. To get the arcsine of an angle you press [SHIFT][SIN], then enter the angle measure in the appropriate unit (degree in your case) and press ENTER. Your result should be 15.01073397 or 15, to nearest degree.

I wonder if your calculator is set to the wrong units. Your calculator can be set to degrees, radians, or gradians. I assume that you want it set to degrees.

When I click 1 2nd and cos, I will always get 0, because using the 2nd before the cos turns the function into cos^-1 (inverse cosine). The inverse cosine of 1 is 0 because the cosine of 0 is 1.

Good luck.

Let me know if you have any further questions.

Press SIN 4 3 2ND [ANGLE] 1 3 0 2ND [ANGLE] 2 ENTER

2ND [ANGLE] 1 gives you the degrees symbol, 2ND [ANGLE] 2 gives you the minutes symbol. If you need seconds, use ALPHA ["] (on the + key).

Note that this usually won't give you an EXACT value, but only a ten-digit approximation.

First, make sure you have the appropriate angular mode set. To change the angular mode, press MODE, use the arrow keys to highlight either "RADIAN" or "DEGREE" on the third line, press ENTER, then press 2ND [QUIT].

Press the appropriate sin, cos, or tan key (two rows above the 7, 8, and 9 keys), enter the angle, close the parenthesis, and press ENTER. For example, to calculate the sin of 2.1, press

SIN 2 . 1 ) ENTER

Press the appropriate sin, cos, or tan key (two rows above the 7, 8, and 9 keys), enter the angle, close the parenthesis, and press ENTER. For example, to calculate the sin of 2.1, press

SIN 2 . 1 ) ENTER

To set the calculator to degrees, press DRG and select DEG.

To calculate the arcsin, press 2nd SIN followed by the value of the sine. For example, if the width is 3 and the length is 5, press 2nd SIN 3 / 5 ) ENTER.

First, make sure the calculator is set to degrees (2nd [FORMAT] down-arrow).

Put in the value, press INV, the appropriate function key, and =.

For example, to find the inverse sine of .3, press

. 3 INV [SIN] =

Assuming you're in degrees mode instead of radians, press diamond then ENTER to convert a symbolic result to decimal.

This can be done in one step by using diamond ENTER instead of ENTER when first calculating the expression. For example:

2ND [SIN] 5 ) diamond ENTER

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.

here are the steps in changing it from radian to degrees

1. turn on your TI-83 plus

2. press the MODE button near the top of your calculator

3.go down to options and move the highlight from radian to degree, press enter and clear

you're good to go
