## tand function in excel?

(OP)

I found an equation in a Journal article and I'm trying to write it into a spreadsheet. The problem is 1) I'm not sure what the tand functional actually is and 2) Excel doesn't seem to have it as a built in function. One of hte footnotes told me it was a Tangent Delta function, but Google isn't being too helpful in finding out what that means. Can anyone point me towards a resource that explains it? Based on the explanation I'm hoping I can figure out a way to calculate it in Excel. If someone can tell me if it's hidden in Excel somewhere that would also be very helpful.

Generalized a bit, the formula is R = k*tand(C)

Thanks in advance.

Tangent of argument in degrees.

Of course Excel uses radians.

But I suppose I'm genuinely curious and do learn things by doing some digging on occasion.

Do you have some other research you would like the members here at Eng-Tips to perform on your behalf?
