Make sure your calculator is in degrees.

Press Mode, then choose move down to where you have a choice between Degree and Radian. Highlight Degree.

Second-Mode to Quit. You should be set.

How to use tan^2(55)

It's a quirk of notation. When a book says tan^2(x), it actually means (tan(x))^2. Only the trigonometric and hyperbolic functions seem to get written this way. If one wants the square of a logarithm, for example, one doesn't write log^2(x).

The short answer: if you want tan^2(55), calculate tan(55) then square it.

I do not know how to use the tan-1 when square roots are involved.

Use parentheses. If you do not have parentheses (doubtful), calculate first SQRT(2)/2 =
Result is displayed and saved in ANS memory. Now calculate the arc tan of ANS.

Cot(x) = -0.6

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 degrees the answer is -59.036 deg.

I hope this helps you out.

How to I use the tangent mode on my texas instrument calculator. For instant; if I want to solve 14720/tan 2 degrees.

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

14720*2 TAN = 514.034

Using Tan,sin, cosin

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

How to use the cot function

I don't have a Cot button but Cot x = 1/Tan x so enter

1/Tan 78 = 0.212556 etc if you have a fraction button you can write it that way too:

1 frac button Tan 78 = 0.212556 etc
