MATH-125 Year 1 3 credits 12 lessons · 6 h 55 min

Offered by HSM University · Engineering Core

What you'll learn

  • Work with vectors: magnitude, dot product, cross product, angles, lines and planes
  • Form linear combinations, determine spans, test linear independence and find coordinates in a basis
  • Solve systems of linear equations by Gaussian elimination and interpret their solution sets
  • Multiply, transpose and invert matrices and use them to model engineering systems
  • Solve systems with LU and Cholesky factorizations, estimate computational cost, and assess conditioning
  • Compute determinants and interpret them as area and volume scale factors and tests of invertibility
  • Find column spaces, null spaces and rank, and apply the rank-nullity theorem to trusses and circuits
  • Represent rotations, scalings, shears, projections and translations as matrices and compose them
  • Find eigenvalues and eigenvectors, diagonalize matrices and compute matrix powers
  • Use orthogonal projections, Gram-Schmidt and the normal equations to fit models by least squares
  • Apply the spectral theorem to principal stresses, vibration modes and data, and interpret the SVD
  • Formulate engineering problems in matrix form, solve them with appropriate methods and interpret the results
