The thing is that my book states that I can solve this one partly exact.
That is for half of the inifinite solutions.
But I can get nothing of this, no exact solutions at all.
Where am I wrong?
Thanks in advance.
Seems to me it is like as opposed to . I think you're worked that out though because your second last line agrees with my working pretty much.Originally Posted by a4swe
So, I just factorised here to give:
And then solve
that's in radians obviously.
That's what I've figured from it but I'm not 100% sure if I'm right but it looks right to me.
Hello, a4swe!
Am I missing something important?
. . I found all the solutions . . .
And I have no idea what your book means by "exact" solutions.
Why introduce fractions? . . . Don't you hate them as much as I do?
We have: .
Factor: .
And solve:
. .
. .
. . . and those are the exact solutions.
