Stephen's Reflection

Ok so this week has been difficult cause of the tests mainly cause i dont remember a thing but there is stuff i do remeber from a more recent chapeter. Im going to give the identities formulas:

cscΘ=1/sinΘ
secΘ=1/cosΘ
cotΘ=1/tanΘ

sin -Θ= -sinΘ and cos -Θ= -cosΘ
csc -Θ= -cscΘ and sec -Θ= -secΘ
tan -Θ= -tanΘ and cot -Θ= -cotΘ

sin²Θ+cos²Θ=1
1+tan²Θ=sec²Θ
1+cot²Θ=csc²Θ

sinΘ=cos(90°-Θ) and cosΘ=sin(90°-Θ)
tanΘ=cot(90°-Θ) and cotΘ=tan(90°-Θ)
secΘ=csc(90°-Θ) and cscΘ=sec(90°-Θ)

I kinda forget alot of stuff in the last chapeter we did soo i need help with formulas.
