Hey,
1. Homework Statement .
Given,
[tex]
{f(0)} = {0}
[/tex]
[tex]
{{{f}^{\prime}}{(0)}} = {0}
[/tex]
Find the constant [tex]{C}[/tex] for the following and justify,
[tex]
{{\frac {1}{2}}{{\left({f(x)}\right)}^{2}} + {{\left({{{f}^{\prime}}{\left({x}\right)}}\right)}^{2}}} = {C}
[/tex]
2. Homework Equations .
Calculus.
3. The Attempt at a Solution .
This problem is take from the proof of another problem and I follow what they're doing in that proof all except these last lines,
http://d.imagehost.org/0790/line.jpg
I don't get exactly how from: [tex]{{f(0)} = {0}}[/tex] and [tex]{{f^{\prime}{(0)}} = {0}}[/tex]; they're able to determine that the constant is zero ([tex]{{C} = {0}}[/tex]).
How do they determine that?
Thanks,
