Question

Linearization?

Answer 1

f(x) = tanx a=pi

Answer 2

f'(x) = sec^2x ?

Answer 3

the linear function y is given by
y= f(a) + f'(a) (x-a)
here , a =pi,
f'(x) = sec^2 x

whats f(a) =... ?
just replace 'x' in f(x) by a =pi.

whats f'(a) =... ?
just replace 'x' in f'(x) by a =pi.

Answer 4

f'(pi) = 1?

Answer 5

f(pi) = tan(pi) = 0

Answer 6

L(x) = 0+ 1(x-pi)

Answer 7

absolutely correct!

Answer 8

ohhh ok thanks!!

Answer 9

welcome ^_^
