Question

Linear Approximation...?

Answer 1

Linear Approximation. Ah how I love thee. Until you went and got all confusing on my in 3D.

Answer 2

\[\color{red}{{\text{Construct a linear approximation of }}y = \tanh \left( x \right){\text{ near c}} = \ln \left( 2 \right) \approx 0.693}\]\[\color{red}{{\text{ and use \it too approximate the value of}}\tanh (0.7)}\]

Answer 3

L(x) = f(a) + f'(a)(x-a)

Answer 4

Is a 0.7 or ln(2) or 0.693?

Answer 5

a = c in this case
