What units are the outputs of trig functions measured in? I was in calc today and somebody asked that question and the teacher didn't know and I couldn't find an answer on google. Anybody know the answer?

Looks like what I drew on the inside of my calculator to get through calculus...

Yea think of sin/cos as operators, they act on an input and generate an output, no need to have units

You work with the units given. If there are none, you just answer with unitless values

It's unitless. Think about sin(x)=opposite/hypotenuse~distance/distance

Calculus is distance (on time to a power for derivatives) usually. Is that what your looking for? Trig doesn't have units.

How do you people understand this shit? I try so fucking hard and I just cannot grasp it. It's fucking infuriating.

You get a solid base in algebra and it all becomes simple really. Maths makes sense. Just follow the rules.

tan(x) = a/b, where a and b are the legs of a triangle. These can be expressed as lengths. Thus, the output is unitless.

That makes a lot of sense. Thanks n

To my (precal) knowledge, either radians or degrees. (2pi = 360 degrees)

That's the input to trig functions, the output, as noted, is unitless
TommyWa
You're correct. I misunderstood the question.
