Does the equation define y as a function of x?y-x^2=2 相关知识点: 试题来源: 解析 The last equation is a rule that gives one value of y for each value of x, so itdefines y as a function of x. We can writ the function as f(x)=x^2+2.yy-x2=2101 ...
We can write the function as f(x)=x^2+ 2. (2)We try to solve for y in terms of x:x^2+y^2= 4y^2= 4-x^2 Subtract x^2y=± √(4-x^2) Take square rootsThe last equation gives two values of y for a given value of x. Thus, the equation does not define y a...

是不是以X为变量的Y的方程。。用X去DEFINE Y这个意思。
F(x,y,z)=0 is assumed to define z as a function of x and y, that is, z=f(x,y). So by (7), (∂ z)(∂ x)=- (F_x)(F_z) since F_z≠ 0.Similarly, it is assumed that F(x,y,z)=0 defines x as a function of y and z, that is x=h(x,z). Then F(h(y...

Answer to: If z is given implicitly as a function of x and y by the equation e^z - xy^2 z - 2 = 0, then \delta z \delta y is: By signing up, you'll...
Suppose y is directly proportional to x, also suppose y = 7 when x = 9. a) Find a formula for y as a function of x. b) Use your formula to find x when y = 29. Consider the equation (9x - 2y)dx + (10y - 2t)dy = 0. a...
Integrating both sides, the right-hand side does not depend on y and the left-hand side is written as a derivative of a function. Afterward, we solve for y. The method is called the integrating factor method where the function r(x) is called the integrating factor (Lebl, 2022). The ...
