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?

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

Typically trig functions default to radians in most questions involving measurement. But without a diagram you dont have evidence of a unit.

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

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

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

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.

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

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.
