Find the derivative of f(x) = [tex]{cos^{-1}}(x^8+6)[/tex]

Find the derivative of f(x) =

${cos^{-1}}(x^8+6)$

a. f'(x) =

$\frac{{8x^{7}}sin(x^8+6)}{{cos^{2}}({x^{8}}+6)}$

b. f'(x) =

$\frac{{8x^{7}}}{{cos^{2}}({x^{8}}+6)}$

c. f'(x) =

$\frac{{8x^{7}}}{{{sqrt{1-({x^{8}}+6)^{2}}}}}$

d. f'(x) =

$-\frac{{8x^{7}}}{{{sqrt{1-({x^{8}}+6)^{2}}}}}$
