Sin 52 degrees 17 minutes = .791 what buttons do i push to get this answer

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) =.

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.

Let's start with a little background.

The cot(x) is also known as the cotangent(x) and it equals 1/tan(x) which equals cos(x)/sin(x). I'm showing these formulas because your calculator may not have a cot button but it will probably have buttons for tan, cos, and sin.

Your calculator may also have buttons for tan-1, cos-1 and sin-1. These are the inverse functions for tan, cos, and sin. If you enter a number and then push the tan-1 button, the result is the angle whose tangent is the entered number. For example, it you enter 1 and push the tan-1 button the answer will be 45 deg because tan (45 deg) = 1.

Now let's look at the problem, cot(x) = -0.6.
The first thing we need to know is do you want the answer in degrees or radians? Your calculator will have both modes. The default mode when you first turn it on is probably degrees. If this problem is in radians you will need to change the mode of your calculator over to radians before we start.

If cot(x) = -0.6, then tan(x) = 1/-0.6 from the formula I showed in the background section.

This means tan(x) = -1.6666666...

Now we just enter -1.66666667 and hit the tan-1 button to get the answer.

If we're operating in radians the answer is -1.0307 radians.
If we're operating in degrees the answer is -59.036 deg.

I hope this helps you out.

x is the height of tree, y and z are as denoted in picture:

1. cos(22°)=y/215==>y=cos(22°)*215=199.3 ft
   
2. sin(22°)=z/215==>z=sin(22°)*215=80.5 ft
   
3. tan(52°)=(x+z)/y==>x+z=y*tan(52°)=255.1 ft
   
4. x=255.1-z=255.1-80.5=174.6 ft

You may be working in degrees when you need to be in radians, or vice versa.

Press the MODE button until it offers you the choice D R G (Degrees, radians, grads) and select the corresponding number. Then try again.

When entering the information it only shows the degree symbol. If you press enter or type inthe formula, then the answer will show the Degree, Minutes, and seconds. It seems to be the way it was program by Casio. It still seems to work fine for entering that information

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.

hi..
First, you want to make sure the calculator is in degree mode. Hit the "DRG" button until you see "DEG" in the display.

Then do the following keystrokes:

8 x 28 [sin] = ÷ 21 [sin] =

That should get you 10.48021316 in the display.

Hope this helps. Thankyou

Make sure you are set to degrees, radians, or grads, whichever angular measurement you are using.

The DRG key toggles through the three modes of input, and the display shows which you are in.

30 SIN will give the correct 0.5 answer if you are set to use DEG.

Set to RAD and since 30 degrees = (30)(pi)/180= 0.52234 rad, set to RAD and 0.52234 SIN also gives you the correct 0.5 result

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
