- Without using a calculator, determine the following in terms of sin36:
- In the diagram, the graphs of the functions ƒ(x) = asinx and g(x) = tanbx are drawn on the same system of axes for the interval 0° ≤ x ≤ 225°
- Given that sin23° = √k, determine, in its simplest form, the value of each of the following in terms of k, WITHOUT using a calculator:
- In the diagram the graph of f(x) = 2sin2x is drawn for the interval x ∈ [-180°; 180°].
