If someone could just help me get to form a "quadratic" type equation with one variable for these questions, I can take it from there.
I am stuck on part (d) and (e):
Like stated in my other thread, I think I have to use this:
But I can't seem to get one variable to form an equation for these 2.
Any ideas?
Thanks.
EDIT:
Is this right for (e)? I'm just going to swap theta for x because it's easier to type:
tanx * sinx - cosx = 0
tanx * sinx = cos x
tanx * sinx = (sinx)/(tanx)
tan^2 x * sinx = sin x
tan^2 x = 1
