| 1h 28m 28s | Video has closed captioning.

In this video we define the trigonometric functions sin and cos and demonstrate how to prove limits involving these functions using basic inequalities and trig identities. We do the following examples: 1. lim_(x to 0) sin x = 0 at 4:20 2. lim_(x to 0) cos x = 1 geometrically at 6:05, using trig identity at 10:30 3. sin x is continuous on R at 14:45 4. arctan x is continuous on positive R at 21:45 #cbd gummy cherries #cbd vitamins gummies #cbd gummies insomnia #prolife cbd gummies
