Energy Loss at Drops - UQ eSpace
... The writer would like to congratulate the authors for their excellent papers. As clearly indicated by them, few researchers investigated energy losses at drop structures. Most engineering calculations still rely on the work of MOORE (1943), WHITE (1943) and RAND (1955). The authors' paper provides n ...

Section P.4 Linear Equations in Two Variables Important Vocabulary
... only the slope-intercept form to find an equation? Explain. Yes, unless the line is vertical. In cases (b) and (c), it may be necessary to solve for the y-intercept b. In case (c), the slope must be found from the given points first. Is it possible to use only the point-slope form to find an equatio ...

CALCULUS 3: NOTES AND EXERCISES ON CRAMER'S RULE
... In class we proved Cramer’s rule for n = 3. You can find a proof for the general case in books on linear algebra (or by googling “Cramer’s rule”). Try an example yourself with four equations in four unknowns to get a feel for the fact that Cramer’s rule is not a quick method when you have more than ...

Differential equation
A differential equation is a mathematical equation that relates some function with its derivatives. In applications, the functions usually represent physical quantities, the derivatives represent their rates of change, and the equation defines a relationship between the two. Because such relations are extremely common, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology.In pure mathematics, differential equations are studied from several different perspectives, mostly concerned with their solutions—the set of functions that satisfy the equation. Only the simplest differential equations are solvable by explicit formulas; however, some properties of solutions of a given differential equation may be determined without finding their exact form.If a self-contained formula for the solution is not available, the solution may be numerically approximated using computers. The theory of dynamical systems puts emphasis on qualitative analysis of systems described by differential equations, while many numerical methods have been developed to determine solutions with a given degree of accuracy.
