5 resourcesEquations of Trig Graphs
Find y = a sin(bx + c) + d or y = a cos(bx + c) + d from the graph and one or two marked points: one of a, b, c, d, then two and three (never b and c together), then all four, then challenges (the same graph as a sine and as a…

A sentence explaining one of the unit’s key words, with gaps. Pick the right word for each gap from the words scattered round it: the right ones and plenty of wrong ones. A deck for every unit.
🧮 ToolGraph Plotter
A graphing calculator: type y = f(x), x = g(y), implicit relations such as x² + y² = 25, inequalities (shaded, dashed for < and solid for ≤), parametric and polar curves, points and tables, functions f(x) = … with f′(x), and…
🔗 MatchingTransforming Trig Graphs: Matching
Twelve graphs of sin x, cos x and tan x (0° to 360°), each with a key point marked, in look-alike pairs: drag each equation onto its graph. Easy: one transformation each. Medium: two, never both inside the brackets. Hard: 24…
