[ boldsymbol{ left[ begin{array}{ccc} 3 & -5 & 1 \ 1 & 1 & 1 \ -1 & 5 & -2 \ 3 & -7 & -8 end{array} right] }]This question aims to learn the Gram-Schmidt orthogonalization process. The solution given below follows the step-by-step procedure. In Gram-Schmidt orthogonalization, we assume the first basis vector […]

[f(x,y,z) = y^2e^{xyz}, P(0,1,-1), u = <frac{3}{13},frac{4}{13},frac{12}{13}>] This question aims to find the rate of change or gradient and projections of vector spaces onto a given vector. Read moreFind a nonzero vector orthogonal to the plane through the points P, Q, and R, and area of the triangle PQR.Gradient of a vector can be found using following […]

For the given set of all vectors shown as $ W=left[ begin{matrix}4a + 3b\0\ begin{matrix}a+b+c\c – 2a\end{matrix}\end{matrix}right] $, and here a, b and c are arbitrary real numbers. Find vector set S which spans W or give an example to show that W is not a space vector. In this question, we have to find […]

The question aims to find the value of an unknown variable given in 3D vector coordinates and the angle between those vectors. The question depends on the dot product of two 3D vectors to calculate the angle between those vectors. As the angle is already given, we can use the equation to calculate the unknown […]
