Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am dealing with a function f(x) involving various complicated trig functions. I took the first derivative of the function f(x), which is doable, and set it to zero to find the at which value x the function f(x) would be maximum. However, once I have the derivative of f(x), it does not seem possible to isolate x and solve for it...

What does it mean to solve the problem numerically? Does it simply mean taking the function representing the derivative, plugging in a series of x values, and searching for the value(s) that make the function zero?

Thanks
