1. The problem statement, all variables and given/known data Can someone please help or guide me with these problems. Thanks in advance. less than or equal to = </= 1 (x+3)(x-3)>0 2 x^2-2x-15</= 0 3 sin2x=sinx, 0</=x</=2pi 4 logx+log(x-3)=1 3. The attempt at a solution OK so for number 1 I do not know where to start. For number two I factor it and I'm in the same spot as number 1. As far as number 3 is concerned I do not know where to start. Number 4 I know that I have to condense the logarithms into one but I'm not sure what to do afterwards.
