Common Core Aligned Resources for HSF-TF.A.3
(+) Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosines, and tangent for π-x, π+x, and 2π-x in terms of their values for x, where x is any real number.

Steady-State Circuit Analysis & Filter Design
9th - Higher Ed CCSS: Designed
Scholars identify how the TI-89 implements phasors to perform sinusoidal steady-state analysis. The focus is on how to enter and display complex numbers. They also show how a typical steady-state application how to use the Numeric Solver...
Investigation the Derivatives of Some Common Functions
9th - 12th CCSS: Designed
Students investigate the derivative of a function. In this calculus lesson, students explore the derivatives of sine, cosine, natural log, and natural exponential functions. The lesson promotes the idea of the derivative as a function...
The Unit Circle and Special Triangles
9th - 11th CCSS: Designed
Students identify the properties of right triangles. In this geometry lesson, students identify the different ratios and parts of a Unit Circle. They use the unit circle as an aid in finding parts of a special triangle and trig identities.
Trigonometric Functions: The Unit Circle
10th - 12th CCSS: Adaptable
This comprehensive problem and note set walks the class through a large part of simplifying trigonometric expressions using the unit circle and identities. From identifying angles to applying appropriate trigonometric ratios, problems...
Extending the Domain of Sine and Cosine to All Real Numbers
10th - 12th CCSS: Designed
Round and round we go! Pupils use reference angles to evaluate common sine and cosine values of angles greater than 360 degrees. Once they have mastered the reference angle, learners repeat the process with negative angles.
