Can someone please help or guide me with these problems.
Thanks in advance.
less than or equal to = </=
(x+3)(x-3)>0
x^2-2x-15</= 0
sin2x=sinx, 0</=x</=2pi
logx+log(x-3)=1
To learn how to solve polynomial inequalities, try here.(x+3)(x-3)>0
x^2-2x-15</= 0
To learn how to solve trig equations, try here.sin2x=sinx, 0</=x</=2pi
To learn how to solve log equations, try here.logx+log(x-3)=1
A good first step would be to move the sine to the left-hand side, apply the double-angle identity to the first sine, and then factor. Then solve each factor.Thank you it all helped. I am stuck however on the trig equation. I am not sure what to do after I get 2sin(x)cos(x)=sin(x).
