to find, for example,dy/dxanddz/dxas functions ofx, y, and z, and the problem reduces to integration of a system of two ordinary first-order differential equations. If this system is solved, a two-parameter family of curves is found, from which we determine the one-parameter family of ...
eq1= w + D*lambda*unos==ceros Unrecognized function or variable 'lambda'. solve(eq1,w) %end The right answer is w = -D*lambda*unos But instead, I get the following message: Check for incorrect argument data type or missing argument in call to function 'solve'. Please help...
In Sect. 3, we reduce boundary value problem to a difference equation and we prove the necessary and sufficient conditions for the existence of its solution. In Sects. 4 and 5, we find the solution of the difference equation for \Phi \neq 3\pi /2 and \Phi = 3\pi / 2, respectively...
to find the frequency; as we know that, \(\begin{array}{l}c=\lambda \times v\end{array} \) \(\begin{array}{l}v=\frac{3 \times 10^{8}}{525}\end{array} \) hence, \(\begin{array}{l}v = 5.71 \times 10^{14}/s\end{array} \) to find the energy; as we know that \...
CP2 = det(A - lambda*eye(size(A))) CP2 = Can we find the roots of that polynomial? You can use solve, or you could extract the coefficients, and then use roots. solve(CP2) ans = Are they the same as the eigenvalues, as given by eig?
【解析】 Set up the formula to find the characteristic e quationp(λ). p(λ)=i.(A+(- $$ \lambda I _ { 2 } $$)) Substitute the known values in the formula. p(x)=([-{2}0},½{2}{2}}-}[½{b}{a}a}a}) Subtract the eigenvalue times the identity mat rix from th...

I have a data set, FR, atttached. I am trying to plot the confidence levels for the same but I am encountering a warning message :"Warning: Equation is badly conditioned. Remove repeated data points or try centering and scaling.". I dont know what i...
For an NxN matrix there are lots of solutions, since for the + sign in front of the sqrt you have an independent choice of +- for each element of lambda, so 2^N in all. 댓글 수: 1 Umer Abdullah 2017년 12월 31일 Hi David, Thanks a lot for this. Indeed a closed...
Find the value(s) of x for which f (x) = g (x). f (x) = x^4 - 2 x^2, g (x) = 2 x^2 Find all values of x for which 4sin(x) = -4. Find the values of \lambda for which y = e^{\lambda x} satisfies the equation y + y' = y''. ...
