The answers to the questions
The sine increases from 0 to 90 degrees and from 270 to 360 degrees
The sine decreases from 90 to 270 degrees
The cosine increases from 180 to 360 degrees
The cosine decreases from 0 to 180 degrees
Sine = 0 at 0 and 180 degrees
Cosine = 0 at 90 and 270 degrees
Percent of decrease :
Original - New / Original
so...
80 - 52 / 80 ---->
28/80
.35 multiply by 100 to get percent
35% increase Hope I helped if you have any questions let me know! :)
