Question about Texas Instruments TI-83 Plus Calculator

# Sin cos tan

My textbook states that the solution of tangent 37 is 0.7536, but when I enter TAN 37 ENTER in my calculator it comes up with -.8407712554. Do I have to program it to a certain criteria to get the answer. Any help would be appreciated.

37 is in degrees. so if your dealing with degrees you need to go to and change the mode. hit the mode button next to the 2nd button and go down to and change it from degree from radian by going to degree and hitting enter

### How do I find the tan of an angle and given the tan value, how do I find the angle

To find the tangent of an angle:

1. input TAN (it's up one and left one from the division key)
2. then the desired angle
3. then a close parenthesis
4. And then hit ENTER

To find the inverse tangent:

1. Press 2nd
2. Press TAN (TAN-1)
3. Enter the desired tangent value
4. close parenthesis
5. hit enter

this will give you the angle that yields that tangent value.

You might have to switch your calculator from radian to degrees or from degrees to radians to get the expected result. To do that:

1. Press MODE
2. Scroll down to where it says ANGLE
3. change it from either RAD or DEG

Good luck

### I have a TI 84 plus silver ed. I am trying to find out the inverse tangent. How do I get the answer in degrees?

Hello,
The inverse tangent or arctangent shares the ame key as tan. You access it by pressing [2nd][tan] number [)] [ENTER]. Be warned! The angle value displayed is the same as the one set in [MODE].
Hope it helps

### Sin,cos,tan answers arent coming out right. They are off by a couple of numbers Ex: tan 36.7 enter 7 divided by 60 then add 36 and i get .729658205 instead of .74537703

Hello,
What you deplore is perfectly normal.
7/60= 0.1166666667 the last 6 has been rounded to 7 (result is periodic)
36 + 7/60= 36.1166666667
36.7 -36-7/60=0.8166666667
tan(36 + 7/60) = 0.7296582051

Compare the tangents of two close numbers
tan(36.7)= 0.7453770282
tan(36.66666667)=0.7444724166

True, the precision of calculator is limited, but the number of digits it can display has a lot more precision that real-life problems really require.

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.
