Two workers are pulling on ropes attached to a tree stump one of them pull by 50 N and another one pull by 40 N the angle between tow forces is 60 degree . Find the magnitude and direction of the resultant force on the tree.
the straight line l has equation r=i+6j-3k+s(i-2j+2k). the plane p has equation (r-3i).(2i-3j+6k)=0. the line l intersects the plane p at the point A. Find a vector equation for the line which lies in p, passes through A and is perpendicular to l ?
Suppose that {v1.....Vn} is a basis for the vector space V. Given any vector v element of V, we can express v as a linear combination v = X1V1+.....+XnVn. The uniqueness of this expression means that mapping v to the n-tuple of coefficients (X1...Xn) defines a function O: V - R^n. Prove that this function is a bijection.
