is there no way to find the point but by approximation?

Thanks

This is way to complicated, I dont even see which formula are relevant for my level of mathematics. I'd need a site on which the basic rules are listed, which i need for basic calculus exercises. Unfortunately i either found way to complex or way to simple sites...
