Question

Find the linearization of
f(x) = 6 cos x at x = −/4.

Answer 1

"Find the linearization of..." just means find the equation of the tangent line at some particular x value.

btw, at x = what???

Answer 2

i said x= -1/4

Answer 3

x = -1/4 ???
or is it
\(\large x=-\frac{\pi}{4} \) ???

Answer 4

do you have f'(x) = ???
