Question

is this true, because sin(-t)=-sin(t) it can be said that the sine of a negative angle is a negative number.

Answer 1

Not always

Answer 2

all sin(-t)=-sin(t) is saying is that sine is an odd function

Answer 3

so its false?

Answer 4

the angle -315 degrees is equivalent to positive 45 degrees

Answer 5

What is sin(-270)?

Answer 6

and the sin of 45 is positive

Answer 7

so it is false

Answer 8

\(-1\le \sin \theta \le 1\)

and the same will be true for \(-\theta\)
