Homework Statement
3/(2√3)=cos(3t+4.189)
and therefore,
0.866=cos(3t+4.189)
I need to solve for t.
The Attempt at a Solution
I know that cos^(-1)θ has 2 values for every 2 pi, that is at 30 and 330 degrees.
But there is no limit given, so its probably from 0 to infinite,thus the question wants me to form a new series whereby by substituting n=0,1,2,3 and etc, I will be able to find t.
I don't know how to form this new formula/series as I was not thought this chap in calculus 2 (my lecturer was way behiind schedule, hence she skipped it)
Hope you guys can help me.
Thanks alot.
