Geometry ! (Trigonometry)

PaPreciousVang:

How do you solve for an angle when you are working with trigonometry ?

you use inverse trig.

For example if
sin(theta)=3/4 then

inverse sine (3/4) = theta

inverse sine (3/4) might look like
sin ^-1(3/4)
[Don't confuse inverse sine with a power of -1 . It looks the same but it means something completely different.]
or
asin(3/4)

a stands for arc which means the same as inverse

In your calc you probably need to press 2nd function sin to bring up this function.

Thanks so much ! your explanation helped a lot . its actually a better explanation that the math book .

Thank you, I am a maths teacher, and some text books are not very friendly
