Finding the Equations of Trig Functions from their graphs

Finding the Equations of Trig Functions from their graphs

This allows students to practice finding the equation of trigonometric functions from the given graphs. The worksheet starts with equations of the form y = af(bx) and builds up to the general case y = af(b(x-c) + d. The first sheet's graphs are in degrees and are a mixture of sine and cosine. The second sheet's graphs are a mixture of trig graphs in radians and transformations of y = e^x and y = x^2. Especially useful for IB standard Level - which often asks this kind of question.
