Let \( x, y, z \) be (non-zero) vectors and suppose \( w=2 x-y-3 z \). If \( z=2 x-y \), then \( w=x+\quad y \). Using the calculation above, mark the statements below that must be true. A. \( \operat2 answers -
Let \( x, y, z \) be (non-zero) vectors and suppose \( w=-8 x-2 y+z \). If \( z=4 x+y \), then \( w=x+\quad y \). Using the calculation above, mark the statements below that must be true. A. \( \opera2 answers -
Boundary value problem y(x, 0) = f(x), dy/dt(x, 0) = 0, y(1, t) = 0 y(x, t) is definied for 0 ≤ x ≤ 1, t > 0.
6. Resuelva el problema de valores de frontera \[ \frac{\partial}{\partial x}\left(x \frac{\partial y}{\partial x}\right)=\frac{\partial^{2} y}{\partial t^{2}} \] Dado que \( y(x, 0)=f(x), y_{t}(x, 0)0 answers
