I need help calculating the vectors

Resolve the following vectors into components: (a) The vector v in 2-space of length 5 pointing up at an angle of 37/4 measured from the positive r-axis. U (b) The vector w in 3-space of length 3 lying in the yz-plane pointing upward at an angle of 7/6 measured from the positive y-axis. U 25 Activate 5. Find all vectors @ in 2 dimensions having | |) = 17 where the j-component of v is 8 j. vectors
