y= cos(x-4) -8 cos(x-4) = y+8 x-4 =cos^{-1}(y+8) x=4+ cos^{-1}(y+8) so the inverse is 4+ cos^{-1}(y+8)

y=cos(x-4)-8 (you should define a domain for this function that will make the function 1 to 1) y+8=cos(x-4) cos^{-1}(y+8)=x-4 cos^{-1}(y+8)+4=x f^{-1}(x)=cos^{-1}(x+8)+4

cos^{-1}(1/2)=a cosa=1/2 so a=pi/3 sin^{-1}(sqrt{3}/2)=b sinb=sqrt{3}/2 so b=pi/3 sin(pi/3-pi/3)=sin(0)=0

let a be the first thing, b be the second and expand

also you can just put it in you calculator and then look at the fractions to see which one it is

you can express tan inverse in terms of cos inverse as tan^(-1) (a/b)= cos^(-1) (b/sqrt(a^2+b^2)) then use cos^(-1) a + cos^(-1) b formula to find the answer
