1.1.40 Vector Algebra
Condition: the coordinates of the peaks of the pyramid \ (a (4,2,3,); \ quad b (-5; -4; 2); \ quad C (5; 7; -4) \ quad \) and \ (D (6.4, -7) \). Find A) the volume of the pyramid; b) the cross -sectional area passing through the middle of the rib \ (a d \) and the vertices \ (b \) and \ (c \); c) the cosine of the angle between the ribs \ (d a \) and \ (d c \).
Vector Algebra is a Branch of Algebra That Studies Linear Operations on Vectors and Their Geometric Properties. In the Security You Will Find Problems on the Decomposition of Vectors, Scalar, Vector and Mixed Products, Coordinates of Vectors in Different Bases and Much More.
