You are all wrong!!
What happens when the angle is abtuse?
Sine (theta) = (opposite/hypotenuse) does not work. In this case, Opposite side by hypotenuse = 1.
So, what is the true definition of Sine(theta)?
No Math book addresses this question.
If you go with the definition of sine (theta) = e^i(theta) = cos(theta) + i Sine (theta), and expanding e^i(theta) in an exponential series, and equating the real and imaginary parts, you get one definition for sine and cosnes as an infinite series. However, how do you relate this to a triangle.
Be honest !!
That s why everyone hates math.
The definitions are rotten!

In a right angle triangle with one of the acute angles being theta, sin(theta) is defined as:
sin(theta) = opposite side / hypotenuse

In a right triangle, it's the ratio of the side oppisite the angle theta and the hypotenuse;
sin of theta = oppiste/hypotenuse

sin theta is shot of
sine theta
in a right triangle ABC right angled at B
then theta is the angle B.
and sin is P/H or Perpendicular divided by hypotenuse
sin theta=
Perpendicular
-----------------
Hypotenuse
Or
P

sin theta is = to opposite/hypotenuse.
cos theta is = to adjacent/hypotenuse
tan theta is = to opposite/ adjacent
This is all in regards to a right triangle.
