Question 927346: Please review my work for trigonometry THANKS?
Find the exact values of each of the five trig values:
tan(7π/2)
tan(7π/2 - 2π/1)
tan(7π/2 - 4π/2)
tan(3π/2) = -1/0, undefined
sin(75π)
sin(5π-4π)
sin(π) = 0
sec(9π/4)
sec(9π/4 - 2π/1)
sec(9π/4 - 8π/4)
sec(π/4)
1/cos(π/4)
cos(π/4) = √(2)/2
sin(-π/6) = -1/2
Please look for any errors including illogical mathematical notion
THANK YOU!

tan(7π/2) =
tan(7π/2 - 2π/1) =
tan(7π/2 - 4π/2)=
tan(3π/2)=
sin(75π) =
sin(5π-4π)=sin(π) =
sin(π) =
sec(9π/4) =sec(3π/2) =
sec(9π/4 - 2π/1)=sec(9π/4 - 8π/4)=sec(π/4)=
sec(9π/4 - 8π/4)=
sec(π/4) =
1/cos(π/4) =
cos(π/4) =
sin(-π/6) =
