Question

Need some help on these 4. 1 is a fill-in the blank, pictures 2&3 are for the same problem- I need help finding the max. y-value. Pic 4 I need help choosing the correct statements that describe that graphs function as well as the last one.

How can the unit circle be used to construct the graph of f(t) - sin(t)? if you think of t as an angle measure in the unit circle then fit) will be the y-coordinate of the point where the terminal angle, 1. intersects the unit circe. With the help of the unit circle, plot (t. Film) for different values of t. For example, at t= - we can add the point to the graph. After plotting several points, connect the points to obtain the graph of fit) - sin(t). lo
