Pre-Calculus - Unit 2 Modeling with Trigonometric Expressions and Functions Week of: 2/17 *for additional curriculum information, please visit the district's resource High School Pacing Guides or Georgia Standards of Excellence Pre-Calculus 2/17 Standard(s): PC.FGR.3.1,PC.FGR.3.2 LT: I can use the concept of a radian to establish the existence of 2π radians in one revolution. SC: I can convert between radian and degree measures. I can find the radian measure for the quadrantal angles. I can use radians in the form of a decimal or in terms of π. I can draw an angle in standard position. I can find coterminal angles. I can identify an angle’s reference angle. Lesson/Activity:Daily 10, Notes on vocabulary and example problems including -Angles in standard position, coterminal angles, positive angles, negative angles, radians,degrees, degree - minute-seconds, supplementary angles, complementary angles ,Resources: Teacher Worksheet OB2915-22 all 2/18 Standard(s): PC.FGR.3.3 LT: I can define the six trigonometric ratios of x,y and r using the unit circle centered at the origin of the coordinate plane. I can interpret radian measures of angles as a rotation both counterclockwise and clockwise around the unit circle. SC: I can use right triangle relations to find the value of the six trig functions. Lesson/Activity:Daily 10,Create the unit circle using right triangles, Use the Unit circle to evaluate point function.
