4 resourcesExact Trig Values
sin, cos and tan of 0°, 30°, 45°, 60° and 90°, then obtuse, reflex and angles over 360°, considering the graphs. Levels 5 and 6: given one ratio (e.g. sin x = 3/5) and the range of x, find another. Six levels, timed, click to…
⚙️ WorksheetProperties of the Trig Graphs
The graphs of y = sin x, y = cos x and y = tan x in degrees: which graph is which, key features (period, maximum and minimum, where they cross the axes, asymptotes, range of values), the unit circle (P = (cos θ, sin θ), tan θ as…

🧮 ToolUnit Circle and Trig Graphs
Drag P round the unit circle (or press Play) and watch its height draw the graph of sin θ beside it; for cos θ the graph is turned to sit under the circle with its θ-axis pointing down, so the distance across lines up, with the…
