Trigonometric Graphs and Equations

Over what interval does the syllabus ask you to recognise, sketch and interpret the three trigonometric graphs?

0° ⩽ $x$ ⩽ 360°, for y = sin $x$, y = cos $x$ and y = tan $x$.

Beyond a right-angled triangle the angle is no longer restricted to acute values, so all three are defined for every angle.
