10th grade Trigonometry- tangent ratio

[introspection]

Solve for angle y in the following right triangle using tan ratio:
Opposite Angle = n
Adjacent Angle = 2n
Hypotenuse = n radical 5 (How do I write a radical sign?)

From the (regular MS Desktop) keyboard you can :

(press and hold ALT key down) and type 251 in the "number pad"

and you'll get √

Looks like you are stuck in the beginning - so let's start with definitions.

What is the definition of "Tan" of an angle in a right triangle?

Opposite Angle = n

Adjacent Angle = 2n

Are you trying to say that the SIDE of the triangle which is opposite to angle y has length n?

Likewise, the adjacent SIDE is 2n?

radical 5

How do I write a radical sign?

Subhotosh's method does not work for me (another Windows bug, me thinks).

You may also copy-and-paste the square-root symbol (in Windows, use the Character Map).

Or, you may simply type the characters sqrt(5) for √5.

Requirements:

For desktop Key board (with separate NUM PAD) - make sure NUM LOCK is on. Hold down [Alt] key and type 251 in the NUM PAD.

For laptop key-board, the [Fn] & [Alt] keys must be held down - then type kij [that would be 251 in Fn key] to get √

These are ANSI codes - should work on any key-board.

I agree that this shortcut-method ought to work, but it does not always work.

For example, my laptop has a desktop keyboard (i.e., full-size keyboard including 10-key pad). If I were to restore this system to its out-of-the-box state, then your instructions above for desktop keyboard would work on my laptop. However, I've changed some default Windows-options, and my current configuration does not allow your shortcut method. (Another example is the WIN key; most people only push it once, to display the Start Menu. I need to push it three times.)

Your instructions work for me, on the desktops at the Seattle Public library (but a number of other features are "broken", on their setup). Your method did not work for me, on SCCC lab notebooks (but that's been a while).

I still think it's a function of how Windows is configured. WIN some, lose some.
