Questions & Step-by-Step Solutions

What is the angle between the vectors u = (1, 0) and v = (0, 1)?
  • Step 1: Identify the vectors u and v. Here, u = (1, 0) and v = (0, 1).
  • Step 2: Understand that the angle between two vectors can be found using the concept of perpendicularity.
  • Step 3: Check if the vectors u and v are perpendicular. Two vectors are perpendicular if their dot product is zero.
  • Step 4: Calculate the dot product of u and v: u · v = (1 * 0) + (0 * 1) = 0.
  • Step 5: Since the dot product is zero, this means the vectors are perpendicular.
  • Step 6: Conclude that the angle between the vectors u and v is 90 degrees.
