A regular hexagon has vertices at 1-2i, 0, a, b, c, and d clockwise in that order, as in the picture below:
Then what is Im(a)? Btw, Im stands for imaginary axis
Im(a) = sqrt(3).
That's wrong
Here are some useful equations:
I'll let you fill in the numbers.
How can I find sin(a)?
The first equation allows you to calculate \(\theta\)
Then you can calculate \(\beta\) from the second equation
Then you can calculate \(\alpha\) from the third equation
Then you can calculate \(\sin \alpha\)
Nevermind thanks for all the help!
