2 dni temu · Patterns and Relationships: Recognize the inherent symmetry and relationships between trig functions. For example, sine and cosine are complementary functions (sin(x) = cos(90° – x)), and tangent is the ratio of sine to cosine (tan(x) = sin(x)/cos(x)). Trigonometric Table: Create a table with angles and corresponding values for each trig ...
