Answer 1

What is the maximum value of sin(x)?

Answer 2

i dont know

Answer 3

The maximum value of sin(x) is 1 and thus sin(x) can never reach 2. :D

Answer 4

hmm~ how can you say the maximum value of sin(x) is 1? any proof?

Answer 5

Well, if you have some knowledge in calculus, I could explain. :D

Answer 6

Or we can look at the unit circle.

Answer 7

\[\sin\theta = \frac ph\]
