Just published an Introduction lecture to Trigonometry part of UNIZOR.COM. Presented trigonometric functions on the unit circle and explained the connection with right triangles. Also explained why we can use trigonometric functions as functions of angles referring to a property of similar triangles to have congruent angles and proportional sides.
Video on this topic is coming soon.
