Best ResponseYou've already chosen the best response.2\[\Large\rm \sin(3x+13)=\color{orangered}{\cos(4x)}\]Since sine and cosine are cofunctions, can't we just do this? \[\Large\rm \sin(3x+13)=\color{orangered}{sin\left(\frac{\pi}{2}4x\right)}\]And then,\[\Large\rm 3x+13=\frac{\pi}{2}4x\]Which gives us one solution... x=1.6327...
