Step 1
Use sin(360+α)=sinα
Step 2
sin390
=sin(360+30)
=sin30
=12=0.5

Guided Proof Let v1,v2,....Vn be a basis for a vector space V.
Prove that if a linear transformation T:VV satisfies
T(vi)=0 for i=1,2,...,n, then T is the zero transformation.
To prove that T is the zero transformation, you need to show that T(v)=0 for every vector v in V.
(i) Let v be the arbitrary vector in V such that v=c1v1+c2v2++cnVn
(ii) Use the definition and properties of linear transformations to rewrite T(v) as a linear combination of T(vj) .
(iii) Use the fact that T(vj)=0
to conclude that T(v)=0, making T the zero transformation.

Analyze fx(x)=4sin(3x6)2 using our “trig language” (amplitude, period, etc.) and relate each trig feature to the transformational analysis we’ve done throughout the semester. In other words, state both a transformation, such as shifted left 118 units, and the corresponding “trig language,” phase shift of 118 units left. Be sure to include all transformations and trig features.
