Time scale calculus for dynamic equations on a cantor set.
Any place you need decent support for equations, or proper figure and table management, it's a godsend.
But the formulas are often complex, and homeowners looking for easy equations to check their tax figures will be out of luck.
It is an overarching statement about the possible solutions for certain equations.
This is usually the method we use for complicated ordinary differential equations.
This result also holds for equations of higher degrees.
The approach illustrated above works for equations more general than the wave equation.
In those days, he was one of the greatest experts for differential equations.
Likewise, despite much interest, the problem for equations over the rationals remains open.
He shook his head, keeping a wary eye out for phantom equations.
