Therefore since the trig equation we are solving is sin and it is positive (0.5), then we are in the 1st and 2nd quadrants. We have already found the first solution which is the acute angle from ...

To get the other solution, we need to go back to our quadrants and use the appropriate rule: Therefore since the trig equation we are solving is sin and it is positive (0.5), then we are in the ...

Interestingly enough, the trigonometric functions that define those relationships are also closely tied to circles. Needless to say, this makes trig one of the hardest topics in math for students ...
