Is there a function for natural trig outputand not radians ie sine(45)=.70711?

Like this?

That works. Thanks much!

You are welcome.

You may also use the degree sign ° instead of deg, if thats more natural for you.

To follow up on Werners suggestion, the degree sign can be inputted using the shortcut Alt+0176.

Or (depending on you national keyboard) by simply pressing the appropriate key 🙂

Better

Not a chance

Why not?

Not that big a problem with symbolic evaluation in Mathcad 15 and below, where you can hide keywords and let the evaluation look like an =

You have to define the degree sign, because the symbolics doesn't know about that "unit".

Just seems a little too much effort for little reward

No, it was a numeric answer

When I was new to this forum I often wondered why people would prefer writing deg instead of the usual degree sign °. It took me a while until I realized that the degree sign is missing on the English keyboard layout and therefore its only available by an uncomfortable series of keystrokes and/or by copy and paste.

On German keyboards its at the upper left next to the 1 and easily accessible. Many other national keyboard layouts support the degree sign, too.

I have never really noticed it was missing as I have always used the shortcut.

Another English trait hey!!!!!

Just looked it up. It seems the ° is missing on the US keyboard, on the UK keyboard its on the 0-key accessible with AltGr-0.

That doesn't work for me.

It's Alt+0176 = ° or if you want a bigger one Alt+0186 = º

So the information here is not correct? http://ascii-table.com/keyboard.php/168

The latter is not recognized as degree by Mathcad and may look, depending on the program, like an underlined degree sign - in MC it looks normal.

Here what the two characters look like in Word - guess its dependable on the used code page.

No I don't think so. My keyboard does not have a degree sign anywhere.

Or, in MC15 (Prime ?), you can use inset unit from the toolbars as shown below: degree_unit.png

It works for numerical results as per the original request.

It was a computer Wang 2200 - see please http://en.wikipedia.org/wiki/Wang_2200 (a Russian version Искра-125 see the picture). I have created the first my simulator with it.

The BASIC of this computer has three operators

SELECT R (default, as in Mathcad now)

SELECT D (degree)

SELECT G (grad: 2pi=400 grad)

One my student has selected not SELECT D (for sin(45) etc) but SELECT G (G - градус [gradus] degree in Rusian).

It was very interesting to see, how this student has tried to debug a program

It was also a good joke for 1-th April!
