Guys I really appreciate all of your help today, as I am trying very, very hard to learn all of this. Thanks to Soroban I am actually starting to grasp this concept, but I have one last question.
Suppose I had
Cos(2x)=3/5 and I know that 2x is in quadrant I.
My Unknown is: tan(x)=?
Since this is equal to 3/5 how would I go about appyling the double angle formula so than I can say cos(x)=adj/hyp, and so fourth. I like putting it into this form because it makes it way easier for me to solve the problem. I know that Cos(2x)=Cos(2+x) and that Cos(2+x)= Cos(2)*Cos(x)-Sin(2)*Sin(x) but I am just not really sure how to implement the 3/5 what would I substitue it for?
Again Thanks for all of your help!
I love this site!
