Homework Statement
Ok so I found out last time that the derivative of the function they asked me to find was:
[tex] \frac {dF}{d\theta} = \frac { - \mu^{2}Wcos(\theta)+\mu W sin(\theta)} { (\mu sin(\theta) + cos (\theta))^{2}} [/tex]
and now they are asking me when is this 0, specifically they want the general formula for theta to be zero and i really don't have a clue where to start. I have looked at a bunch of trig identities to see if anything would help but I can not see anything, sure there are a couple of swaps I could make but it would not quickly make things much easier in the problem. I really don't think it is suppose to be that hard. Perhaps I am over thinking it somehow. I figure that you would just set the equation equal to zero and solve for theta but I really don't know where to start doing that... point me in the right direction!
thanks!
