how do i solve for an exact answer for 0= sinx + xcosx on interval [0,2pi] i got (tanx)/x = -1 but that doesnt really help me

You'll get 3 values that fall in the domain [0,2Pi] : x=0, 2.02875783811 and 4.91318043943 I hope this helps! --Chris EDIT: I got the values for x by solving the equation tan(x)=-x...
