1. The problem statement, all variables and given/known data I can't seem to find online how to calculate the error propogated by trigonometric functions. That is, I know the uncertainty in [tex] \theta [/tex] but am not sure how to deal with it when I apply the tan function. I am quite okay with how to deal with all the basic functions w.r.t. error analysis, just not the trig ones. 2. Relevant equations misc * tan(theta) 3. The attempt at a solution Searched the internet.
