Question: a) Find another angle between 0 and 360 that has the same cosine as 57. (That is, f find satisfying cos() = cos(57) b)

a) Find another angle ϕ  between 0 and 360 that has the same cosine as 57. (That is, f find ϕsatisfying cos(ϕ) = cos(57)

b) Find another angle ϕ  between 0 and 360 that has the same sine as 57. (That is ϕ satisfying sin(ϕ)=sin(57)

c) Find another anger ϕ between 0 and 360 that has the same cosine as 210. (That is, find ϕsatisfying cos(ϕ)= cos(210)

d) Find another angle ϕ between 0 and 360 that has the same sine as 210. (That is, find ϕsatisfying sin(ϕ)= sin (210)
