The present work is a set of activities aimed at teaching introductory notions of trigonometry to high school, accompanied by an abstract theory of the subject. The activities were developed in free and multi-platform dynamic mathematics software: GeoGebra, and have the intentation to make students realize the behavior of trigonometric ratios of sine, cosine and tangent in right-angled triangle, and also on the unit circle. The other trigonometric functions: secant, cosecant and cotangent are defined and presented graphically. Functions like h(x)=a+b.cos(cx+d), are analyzed focusing on the behavior of their graphics when the real coefficients a, b, cand d vary. Activities are interspersed with theoretical explanations that can be used or ad...
