Hello, I understand that solving an equation like f(x)=0 means finding those values of x that make the equality true. In the case of some difficult trig equations (like sin(x)+tan(3x+2)+cos^2(x)=5 which I just made it) it may not be possible to find an explicit solution. What does that mean? Why is exactly a solution that is called explicit? Is there an implicit solution? I would say that an explicit solution gives the exact x values that render the equation true... thanks!
