MATH 55 - Technical Mathematics II

Course Description

  • Prerequisite: "C" or higher in MATH 50 or in 53 OR placement in MATH 55

Basic numerical trigonometry and further applications of algebra and geometry to shop problems. Intended for students interested in Vocational-Technical programs.

Student Learning Outcomes

Upon successful completion of Math 55, the student will be able to:

  • Define the trigonometric ratios of sine, cosine, and tangent in a right triangle
  • Recognize and use the special triangles: 30/60/90 and 45/45/90
  • Define the cofunctions of the right triangle.
  • Solve right triangle problems using the sine, cosine, and tangent functions, using the calculator
  • Apply right triangle trigonometry to solve a variety of trade problems.
  • Use interpolation tables for trigonometric calculations (optional)
  • Use the Law of Sines and the Law of Cosines to solve oblique triangles
  • Recognize vector quantities and scalar quantities
  • Add vectors by both the tail-to-head parallelogram method and the component trigonometric method, including vectors that are not at right angles
  • Graph the sine and cosine waves

In general, the course is designed to provide the student with the skills and knowledge necessary to solve shop problems by using trigonometry. In addition, it gives the students experience in applying the material learned in Math 50 to more involved kinds of shop problems.
