Continuity of trigonometric functions | Cont. and diff. | Grade 12 | Math | Khan Academy
We prove using limits the continuity of trigonometric functions. We use trigonometric identities to prove continuity for sin(x) and cos(x). We use algebra of limits to prove continuity for tan(x) and cot(x). We also figure out the points of discontinuity of functions other than sin(x) and cos(x). Courses on Khan Academy are always 100% free ...
