in mathematics, the analytical form of the problem of finding those inputs for which two given functions have equal outputs. The functional inputs are usually called unknowns, and the unknowns for which the functional outputs are equal are called solutions or roots. We say that the solutions ...
The problem of finding the current-density distribution on the surface of a microstrip vibrator (MV) in the framework of a thin ideally conducting strip, deposited on a dielectric substrate with one-sided metallization, is reduced to solution of a hypersingular integral equation (HSIE). The ...

finding the equation of the trendline How do I find the equation of the trendline line on the graph (under “more options”) along with the r squared value (coefficient of determination). For an exponential trendline, there is a similar LOGEST function....
CSR Enterprises is evaluating its financing requirements for the coming year. The firm has only been in business for 1 year, but its CFO predicts that the firm's operating expenses, current assets, net fixed assets, and current liabilities will remain at their current proportion of sales. Last...
Maxwell's Fourth Equation expresses the observation that a continuous electrical current I or a displacement current (∂D/∂t) gives rise to a magnetic field. At a distance r from a wire with direct current I, for example, the magnetic field is given by (4.20G)H=2Icr (4.20S)H=I2...
Momentum is not measured is Newtons. A newton is the unit for force, and force is defined as an object's mass times is acceleration. F = ma Unit: kg m/s^2 Momentum is defined as an object's mass times its velocity p = mv
Kajiya then used Laguerre's method for root finding in order to solve the equations; he finds it superior to Newton's method in stability and the property that it converges on the nearest root irrespective of the original guess, and that it is cubically convergent. Others have also exploited...
What is the equation for finding the revenue if you have a pizza selling for $15.00, total cost of $55.00 and labor is $4.00? If the profit function for a product is P(x) = 1500x + 60x^2 - x^3 - 33,000 dollars, selling how many items, x, will produce a maximum profit?
是一种最直观的理解: The optimization of linear regression is equivalent to finding the projection of vector y onto the column space of X. As the projection is denoted by Xβ, the optimal configuration of β is when the error vector y−Xβ is orthogonal to the column space of X, that...
