Question
The function cot 115 degree is equivalent to

Answer
Hello Tripp

cot 115 degree is equivalent to many things. You would have to tell me in terms of what you want to write it.

The function "cot" of any angle is given by

cot(x)=1/tan(x)=cos(x)/sin(x)

where "x" is the angle.

To find the value of cot(115 degree) is straightforward. Your calculator should have a "cot"
function. If it doesn't, just use "tan" and take: 1/tan(115).

Just make sure your calculator is in "deg" (degrees) mode.

Hope this helps, but please let me know if this is not what you were asking.

Cheers,
David

PLEASE READ THIS BEFORE POSTING YOUR QUESTION: While I am glad to offer HELP with problems, I refuse to SOLVE problems. There is a difference. Please do not just copy a question from a texbook or assignment. I WILL REJECT IT. I will only accept questions if, in addition to the statement of the problem, you describe in detail what you have tried so far in order to solve it, and what exactly is the problem you are encountering. In other words where/why are you stuck? I can answer questions at the level of the first couple of undergraduate years (in science and engineering) or below. You can ask me about algebra, trigonometry, basic probability and statistics, calculus, vector calculus, differential equations and Fourier analysis. I will not answer advanced (at the graduate level) math questions. Questions in Spanish are also welcome.
