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

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".

Write it as "tan(x)^2". For example, to calculate the square of the tangent of 1, press 2nd [TAN] 1 ) ^ 2 ENTER .

You can see on the images below graphs of the function **y=tan x** and **y=arc tan x** and calculations for your problem

**y=tan x**

y=arc tan x

y=arc tan x

To find the tangent of an angle:

To find the inverse tangent:

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:

Good luck

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

To find the inverse tangent:

- Press 2nd
- Press TAN (TAN-1)
- Enter the desired tangent value
- close parenthesis
- 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:

- Press MODE
- Scroll down to where it says ANGLE
- change it from either RAD or DEG

Good luck

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

You would enter 14720*2 tan make sure you press = sign after and get your answer.

14720*2 TAN = 514.034

14720*2 TAN = 514.034

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.

Press SHIFT [ATAN] whatever ENTER

ATAN stands for arctangent (inverse tangent, tan^(-1)) and is the shifted function of the tangent key.
