Special Right Triangles (Day 2, Right Triangle Trigonometry) In this problem set, we will explore the ratio of the sides for special right triangles, specifically the 30-60-90 triangle and the 45-45-90 triangle. We will also learn about how inverse trigonometric functions can be used to find angles. Finally, we will introduce three more trigonometric functions: secant, cosecant, and cotangent ...

Special triangles can be used to find coordiantes of points on unit circle. The x-coordinate of every point on the unit circle represents the cosine ratio of that angle . The y-coordinate of every point on the unit circle represents the sine ratio of that angle. To find the tangent ratio of an angle, divide the y-coordinate (sine ratio) by the x-coordinate (cosine ratio) Textbook Page 186 #1-6 ...
