Limits
I didnt really understand the limits of sinx and cosx and how you get there answers. but i do understand that when you have x approaching any number that you plug it in . also i really dont understand the limits of tangent and how to find an interval. Im also having trouble of the continuity .

sin x and cos x when they stand alone don't have limits as x-->infinity because they constantly oscillate from 1 to -1. As x-->constant, however, you can just plug in the constant for the output because it's continuous everywhere.
ReplyDeletelimit of a tangent also depend on where youre looking for the limit for. Can you choose a specific example?
What about continuity? Piecewise? functions? definition?
