We evaluate the limit of arctan(1/x) as x approaches 0 from the right by considering the behavior of 1/x as x approaches 0 from the right and then considering when tangent diverges to infinity. #calculus1 #apcalculus

I came across this video while working on approximating f(x)=arctan(x) as x approaches infinity with a Taylor series by Taylor expanding f(z) about 0 for z=x^{-1}. This gave me some helpful insight on how to think about arctan, thanks!

Explain in a video about cardinal no.
Means
n(AUBUCUD) = HOW much elements and use cardinal principle of inclusion and exclusion
