Answer 1

The answer to your question is in this website: https://mathbitsnotebook.com/Geometry/Trigonometry/TGTrigSineCosine.html

Answer 2

I read through that I still didn't get a full understanding of what it meant?

Answer 3

then answers are the reciprocal. Say the sine was 3/8. The cosine would be 8/3

Answer 4

^
you're confusing it with the inverse sine functions

Answer 5

if \(\theta\) and \(\phi\) are complementary angles then:
1) \(\theta + \phi = 90\)

2)\(sin(\theta) = cos(\phi)\)
