- Finding the Length of a Vector. In Exercises 1-4, find the length of the vector. v=(5,3,4)arrow_forwardExercises Finding a Unit Vector. In Exercises 912, find a unit vector a in the direction of u and b in the direction opposite that of u. Verify that each vector has length 1. u=(3,2,5)arrow_forwardFinding a Unit Vector In Exercises 41-46, find a unit vector u in the direction of v. Verify that u=1. v=1,6arrow_forward
- Vector Operations In Exercises 2932, find a uv, b 2(u+3v), c 2vu. u=(6,5,4,3),v=(2,53,43,1)arrow_forwardVector Operations In Exercises 11-16, find the vector v and illustrate the specified vector operations geometrically, where u=(-2,3) and w=(-3,-2). v=u+warrow_forwardFinding the Distance Between Two VectorsIn Exercises 19-22, find the distance between u and v. u=(1,2,5), v=(3,0,1)arrow_forward
- Vector Operations In Exercises 11-16, find the vector v and illustrate the specified vector operations geometrically, where u=(-2,3) and w=(-3,-2). v=u+2warrow_forwardFinding a VectorIn Exercises 13-16, find the vector v with the given length and the same direction as u. v=3,u=(0,2,1,1)arrow_forwardTrue or False? In Exercises 9598, determine whether the statement is true or false. Justify your answer. If u is a unit vector in the direction of v, then v=vu.arrow_forward
- Finding Lengths, Unit Vectors, and Dot Products In Exercises 29-34, use a software program or a graphing utility to find (a) the lengths of u and v, (b) a unit vector in the direction of v, (c) a unit vector in the direction opposite that of u, (d) uv, (e) uu, and (f) vv. u=(1,18,25), v=(0,14,15)arrow_forwardFinding the Component Form of a Vector In Exercises 1 and 2, find the component form of the vector.arrow_forward
