I tried to solve this Trigonometry question, but I do not know how to solve. I read that the
circle has radius 1 and center at (0.0) as the unit circle is plotted in the coordinate
system. I should record the angles $v$ and $w$ in unit circle so that the following are met:
$v$ is an acute angle with $\sin(v) = 0.9$ and w is an obtuse angle with $\sin(w) = 0.9$
You can see the circle here
i don't know how to solve it, but is it something like : $(\sin(0.9) * 100) - \pi = 75.1910983$ ? please help me out, give me examples and information
