Write a formula to express change in y in terms of change in x. What does __differentiable__ mean in math? Let y = f(x) = 7 - 9x + x^3. a. What is the approximate change dy of y as x changes from 1.00 to 0.95? b. What is the exact change \Delta y?
What is the meaning of algebra in math? Explain the difference between independent, dependent, and inconsistent system. Separate the variables of the equation: { x^2y \frac{dy}{dx} = e^y } Select one: { a) \frac{1}{e^y}dy = \frac{1}{x^2} dx\\b)x^2 dy =\frac{e^t}{y...
The zero product rule (also called the zero product property) is a mathematical rule that involves a product being equal to zero. We can use the zero product property to solve equations of different kinds. Answer and Explanation: The zero product rule, or zero product property, states the fo...
functions f(x), and the corresponding changes in the variables x and y. The notations dy and dx are known as differentials. The process used to find the derivatives is calleddifferentiation. The derivative of a function, y with respect to variable x, is represented by dy/dx or f’(x)....

NYB means "Not Your Business" So now you know - NYB means "Not Your Business" - don't thank us.YW!What does NYB mean? NYB is an acronym, abbreviation or slang word that is explained above where the NYB definition is given.
In this paper we construct all Painlevé-type differential equations of the form (d2y/dx2)2 = F(x,y,dy/dx), where F is rational in y and y′=dy/dx, locally analytic in x, and not a perfect square. No further simplifying assumptions are m... ...
A. Solve the following initial value problem: \cos(t)^2 \frac{dy}{dt} = 1 with y(21) = tan(21). (find y as a function of t.) B. On what interval is the solution valid? (your answer should involv Solve each initial value prob...
The ode45 function is for solving a system of ordinary differential equations numerically. You give ode45 a function that it can call with two numeric inputs and it gives you a numeric solution. If you want to solve an ODE symbolically and you have...
