What
Advanced Trig: Using the sin rule, cosine rule and formula for area of an equation in different context
Trig graphs: To be able to sketch and interpret them
Trig identities: To know that tan(x) = sin(x)/cos(x) and (sin(x))^2 + (cos(x))^2 = 1.
In year 2 you will be learning several more trig identities.Trig equations: To be able to solve trig equations in a given interval. This should include those that are quadratics and trig equations in a multiple of x, eg sin(2x) = 0.34
