preCalculus 2017-2018:
Vector and Polar Notation!
(December)
Chapter 9 ScreenCasts
Chapter 9 was all about Vector and Polar Notation. First we talked about Complex Number arithmetic on the Complex Plane depicting Complex Numbers as Vectors with a Direction (theta=arctan(y/x)) and Magnitude (r=sqrt(x^2+y^2)). We also converted from Polar to Cartesian forms (x=r*cos(theta), y=r*sin(theta)). We played around with CIS(theta) notation, DeMoivre's Theorem and even touched on Euler's Trig Identity!
Then we extended our understanding of Complex Vectors to Vector Sums, Vector Differences and Dilating a Vector by a Scalar. Finally we talked about the differences and applications of the Scalar Dot Product and the Vector Cross Product. We even talked about Orthogonality and the Triple Scalar Product!
