Question

prove that the function sin x is continuous

please help​

Answer 1

$\huge\sf\pink{Answer}$

• The sine of the angle x is the height of the triangle. Can the height of the triangle jump from one value to another, without taking all the intermediate values? Only if you pick up the coin in one place, and put it down in another. If the only way for the value of sin x to jump is if x jumps, then sin x is continuous.
