Section 2 Vector OperationsChapter 3
Objectives
• Identify appropriate coordinate systems for solving problems with vectors.
• Apply the Pythagorean theorem and tangent function to calculate the magnitude and direction of a resultant vector.
• Resolve vectors into components using the sine and cosine functions.
• Add vectors that are not perpendicular.

Chapter 3
Coordinate Systems in Two Dimensions
• One method for diagraming the motion of an object employsvectors and the use of the x-and y-axes.
• Axes are often designated using fixed directions.
• In the figure shown here, thepositive y-axis points northand the positive x-axis pointseast.

Chapter 3
Determining Resultant Magnitude and Direction• In Section 1, the magnitude and direction of a
resultant were found graphically.
• With this approach, the accuracy of the answer depends on how carefully the diagram is drawn and measured.
• A simpler method uses the Pythagorean theoremand the tangent function.
