 Dec10 asked Find and draw the image of the triangle with vertices (2,1), (1, 2), (2,2) Dec9 asked Row Reduction with Cofactor Expansion Dec8 asked Give a context-free grammar to generate the following language $L = \{ a^ib^jc^k \space|\space 0 \leq i \leq j \leq i + k \}$ Nov19 asked Describe the smallest subspace of $M_{2\times 2}$ that contains matrices… Nov19 asked Let $M_{2\times 2}$ be the vector space of all $2\times 2$ matrices. Show that the set of non-singular matrices is NOT a subspace. Nov7 asked Let $B =${$1-t^2, t-t^2, 2-2t+t^2$}. Check that $B$ is a basis for $P_2$ and find $[3+t-6t^2]_B$ Nov7 asked Find a basis for the set of vectors in $\mathbb{R}^4$ in the subspace (hyperplane) $x_1 +x_2 + 2x_3 + x_4 = 0, x_1 + 2x_2-x_3=0$ Nov7 asked How can I prove a basis (for RowA, NulA, ColA, or NulA^T) with orthogonality conditions? Nov7 asked Give an example of a $3$-dimensional subspace of $P_4$ which contains the polynomials… Oct17 asked Explain why a determinant function is a cubic polynomial Oct17 asked Given a parallelepiped, how do I find the determinant given vertices? Oct17 asked Determinants of Variables Oct16 asked Need help with Determining a formula for a Resistance using a linear system for loop currents Oct3 asked Find a $4\times 4$ matrix $A$ where $A\neq I$ and $A^2 \neq I$, but $A^3 = I$. Oct3 asked What do I do if I've been asked to find the preimage of a vector, but the inverse of the Transformation Matrix doesn't exist? Sep12 asked A linear transformation $T$ is defined by $T(x_1, x_2)$ Find the image of the line that passes through the origin and point $(1,-1)$ Sep12 asked Show that the transformation T defined by $T(x_1, x_2)\; = \;…$ is NOT linear. Sep11 asked How do I determine linear independence when I don't know the values of the vectors? Sep11 asked How to solve / set up three equations three unknowns with a matrix?
