Therefore, from the graph of the function, we can see that we should be expecting two solutions: one solution being between 0˚ and 90˚ and the other solution between 90˚ and 180˚. sin x ∘ = 0.5 ...

The graph of y = sin θ The graph of y = sin θ has a maximum value of 1 and a minimum value of -1. The graph has a period of 360°. This means that it repeats itself every 360°.

Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...
