blog post

Our recent lesson (about sinusoidal graphs) caught my interest because before we tackle that lesson, I really have no idea what sine, cosine and tangent has to do with the study of triangles. All I know is how to press those button from the calculator without getting any idea or explanation what those 3 buttons from the calculator are doing in the equations for finding angles and lengths of the sides of the triangle. The graphs Mr. K taught us in our class gives me the idea about what sine, cosine and tangent is really all about.
To everyone, Good Luck For Our Test Tommorow!
