Question about Texas Instruments TI-83 Plus Calculator

First, set the calculator to whatever angular mode you want. Press MODE, down-arrow twice, and highlight RADIAN or DEGREE. Press ENTER to select it and then 2ND [QUIT] to exit the mode editor. Now, use the arcsine function by pressing 2ND [SIN^-1] . 9 6 2 2 ENTER and read the angle on the screen.

To get the tangent of an angle, press "tan", enter the angle, and press "=".

See the example for sin on page E-10 of this manual: http://support.casio.com/pdf/004/fx-82ES_etc_E.pdf, replacing the "sin" with "tan".

When you use trigonometric functions you should always make certain that the angle unit the calculator is configured for is the intended one.

When the unit is set to degree sin(37)=0.6018

When the angle unit is set to radian, sin(37 rad)=-0.6435

Change the angle unit to degree.

When the unit is set to degree sin(37)=0.6018

When the angle unit is set to radian, sin(37 rad)=-0.6435

Change the angle unit to degree.

- Press the MODE button
- Scroll to reach the Angle line.
- Use right arrow to highlight deg and press ENTER to validate.

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

The calculator treats sin(x) as a single unit. You have to enter it as "sin(x)^2". Be careful you don't enter it as "sin(x^2)", which is "sine of x^2". If you want to be sure, you can put in an extra set of parens and go with "(sin(x))^2".

Exponentiation of trig functions is a funny bit of notation. Rarely does the exponentiation operator go into the middle of an expression.

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.

Alot of people seem to be having this problem. Angles can be measured in two units, degrees and radians. Your calculator is currently doing everything in terms of radians. I have an 84 but I'm sure the 83 is similar, go under MODE and look for Degrees and Radians and make sure you choose degrees. if you have to convert 360[degrees] = 2* pi [radians]

(easy to remember, 360deg in a circle, 2pi radians in a circle)

Good luck

inverse sine (sin^-1) gives you the angle when the opposite side length and the hypotenuse, in relation to that angle, are given. therefore, if you want to do sin^-1(x), 0<x<1 for all real triangles
ex. sin^-1(1/2) would equal 30.
if you get a decimal, then go to [Mode] and select degrees instead of radians to get angle measures instead of radians... :)
