Calculate the tangent of 45 then square the result.

If you're asking how to do this on a particular calculator, what make and model?

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.

How do I input into the calculator sin squared 45. The answer is 0.75 but how do I go about it on the calculator?


Sine is the Opposite divided by the Hypotenuse.
Let's use a triangle with both sides equal to 1 and the hypotenuse will be a^2 + b^2 = c^2, or 1^2 + 1^2 = c^2, or c^2 = 2, so c = square root (2).

So in this triangle, the sin 45 degrees is 1/square root 2 or 0.7071.

Sin square 45 is really sin 45 squared. So we get our answer 0.7071 and square it, and we get 0.5.

Good luck.

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.

How do i get my calculator to do the trig problem Tan45=1? It is telling me Tan45=1.61977, and i know that isn't right.

Angles may be measured in three angles:degree, radian and gradians (grads).
tan(45 deg)=1
tan(45 radians)=1.61977
If your problems require angles to be measured in degrees, make sure that the calculator's angle unit is set to degrees.
In RUN screen press [SHIFT][MENU] (SetUp) select the angle line and press function key under the tab Deg (should be F1).

Use the identity tan(x/2)=sinx/1+cosx to solve for the value of tan45 degrees

Setting x/2=45, means that x=90 (degrees)
But cos(90)=0 and sin(90)=1. Thus tan(45)=1/(1+0)=1.

For the Casio fx-9750G II how can I change the sin cos tan into decimal format? I'm not sure i wording this right...

The values of trigonometric functions are real numbers. A few special values are rational such as tan(45 degrees)=1. In general the values are decimal numbers whose decimal representations have an infinite number of digits. Your calculator can only give you an approximation.
So I really do not see what you want.
Some new calculators can give you values with radical (square roots), Calculators with a Computer Algebra System or CAS can do algebra and manipulate roots of higher index.

Cot(x) = -0.6

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.
