note that you should think of as
1. For each of the triangles below, find all the missing sides and angles for each problem. Here is a photo of the angles that need to be found.
2. Graph the following sine waves and list the amplitude, the period, and the phase shift.
A) Y = 4sin(2x)
B) Y = 2sin( ½ x + 90)
thanks a ton in advance guys! this stuff has really been bothering me and i've searched everywhere for solutions or help. i hope you guys can!
for (B), the amplitude is 2, the period is 4pi, the phase shift is -180 degrees, there is no vertical shift, and you should graph it between [-pi, 3pi] ...radians
