Answer to Question #21283 in Calculus for Evelyn

Question

find the magnitude and direction of the vector product of two vectors of 10 units each, which are inclined at 30 degrees to each other.

Answer 1

Vector product.
magnitude = A*B*sin(angle) = 10 * 10 * sin(30 deg) = 10 * 10 * 0.5 = 50;
direction: perpendicular to the plane in which these two vectors lie.
