Does the equation define {eq}y {/eq} as a function of {eq}x {/eq}? {eq}y = 9x^{2} - 6x - 9 {/eq} Function A relation is a function when for every input there is a corresponding single output. This output may necessarily not be unique, but there should be only on...
Determine whether the equation defines y as a function of x. x + 4 = y^{2} Determine whether the equation defines y as a function of x. y= -16. y = 1/x Determine whether the equation defines y as a function of x. Determine whether the equation defines y as a...
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...
Let us now define q=n2−1+1k02∂2∂z2thenQ=1+q If | q | < 1, Q can be formally approximated by the first terms of its Taylor series 1+q≃1+q/2−q2/8+⋯ Taking into account only the first two terms, equation (5.32) becomes (5.33)2∂ψ∂r−ιk0((n2−1)...
You can generate a mesh and define physics by applying material properties, boundary conditions, and initial conditions. Solve the problem by using the finite element method and postprocess the results. Use design of experiments techniques to explore and optimize the design for desired performance. ...
To solve the nonlinear system of equations exp(−exp(−(x1+x2)))=x2(1+x21)x1cos(x2)+x2sin(x1)=12 using the problem-based approach, first definexas a two-element optimization variable. x = optimvar('x',2); Create the first equation as an optimization equality expression. ...
We will define kzB = ±iα such that α is real and >0. If we choose kzB = −iα we obtain a solution in medium B for the electric field whose dependence on z varies as exp(αz). Its amplitude decays exponentially to 0 as z decreases from 0 to −∞. This solution, ...
We usez=g(x,y)to represent surfaceS, wheregis a function of x and y. We defineG(x,y,z)=z-g(x,y). Its unit normal vectornequals: Therefore, using (10) and (14), equation (12) can be written as: This is the formula for a surface to be projected on thex-y surface. There...
