  1. Fundamentals of Mathematics for Engineers Lab ENGR 2194 Lab # 2 – Trigonometric Relationships: One and Two-Link Planar Robots

  2. Inventor Dean Kamen with Prosthetic Arm Real-World Example Related to Topic! Automotive, aerospace, robotics and building design engineers commonly use: Trigonometry Geometrical relationships

  3. Today's Learning Objectives • After today's lab, students will be able to: • Understand the basic trigonometric functions. • Understand the concept of a unit circle and four quadrants. • Understand the concept of a reference angle. • Be able to perform the polar to rectangular and rectangular to polar coordinate conversion. • Prove a few of the basic trigonometric identities.

  4. Reference Angle • Commonly represented as Greek letter ϕ • Less than 90°

  5. Law of Cosines

  6. Law of Sines

  7. MATLAB • Commands (e.g., “disp”) • Functions (e.g., sin/sind, cos/cosd, etc.) • Dot Operators

  8. Important Takeaways • Essential to Engineers: • Trigonometry • Basic functions • Unit circle and four quadrants • Reference angle • Coordinate conversions • Basic identities • Technical Computing • MATLAB
