Hi Raisa,

I assume you just want the values filled in.  

          120      135       150         210         240

sin     sqrt(3)/2   1/sqrt(2)  1/2      -1/2     -sqrt(3)/2

cos         -1/2   -1/sqrt(2) -sqrt(3)/2 -sqrt(3)/2    -1/2

tan        -sqrt(3)  -1       -1/sqrt)(3) 1/sqrt(3)  sqrt(3)

csc      2/sqrt(3)    sqrt(2)   2        -2       -2/sqrt(3)

sec        -2       -sqrt(2)    -2/sqrt(3) -2/sqrt(3)   -2

cot      -1/sqrt(3)   -1      -sqrt(3)     sqrt(3) 1/sqrt(3)


Hope this helps you out.
