using findroot for multiple functions

I need to solve multiple equations varying one parameter. I am able to do this if I vary the parameter in equal steps, but I have a list of numbers that I need to plug in. Here is an example because my description probably is not very clear: Here is an example of what works: Table[t /.FindRoot[(t-a)*Sin[t+a] + Sin[t-a]*Cos[t+a], {t,0}],[a,1,10,.5] My problem comes in because I want have a list of values that are not in equal steps. I have tried the following with no success: list = {1, 3.4, 99.1,100,109} ReplaceAll[[FindRoot[(t-a)*Sin[t+a] + Sin[t-a]*Cos[t+a],{t,0}],a-> list] If anyone has an idea on how I can get this to work, please let me know. Thanks, Amy Sommer
