Transformations of Trigonometric Functions

A Transformations ONLY
A Transformations
  • A = lead coefficient of trigonometric function
  • six cases of A 
    • A = 1 no vertical stretch, compression, or reflection 
    • A = -1 only vertical reflection
    • 0 < A < 1 only vertical compression occurs
    • -1 < A < 0 vertical compression and vertical reflection occurs
    • A > 1 only vertical stretch
    • A < -1 vertical stretch and vertical reflection

Vectors

Vectors 101: Heading and Magnitude
  • DESMOS File
  • this will draw a vector based on its heading and magnitude
  • angles are measured as headings in degrees
  • this will show how heading is measured on a coordinate grid
Vectors 101: Bearing and Magnitude
  • DESMOS File
  • this will draw a vector based on its bearing and magnitude
  • angles are measured as bearings in degrees
  • this will show how bearing is measured on a coordinate grid
Vector Triangle 101: Vector Addition based on heading and magnitudes
  • DESMOS file
  • angles are measured in degrees and based on heading notation
  • this will give lengths of vectors and related angles but NOT resultant vector's heading or bearing
Vectors 101: Component Vectors
  • DESMOS File
  • this will allow for the investigation of vectors that have a direction vector in component form
  • parallel to the vector
  • perpendicular to the vector
  • scalar multiples of the vector
  • from a point not at (0,0)
  • unit vectors
