## help_needed 2 years ago Use a linear approximation (or differentials) to estimate the given number. e^0.01

1. mukushla

ok u just need a linear approximation of $$e^x$$

2. help_needed

So I should still use the f(a) + f'(a) (x-a) ?

3. mukushla

yes and u have$f(x)=e^x$and $a=\text{whatever u want but better and simpler to use 0}$

4. help_needed

ok so let me try this to see what equation i get

5. help_needed

iDK if what i did makes sense. I got f(0) + f'(o)(x-0) = 1 + 0(x-0) = 1

6. mukushla

emm but f'(0) is 1 ha?

7. help_needed

f'(x) = 1/x right so isnt x=0 so that makes it 1/0 = 0.

8. mukushla

f'(x)=e^x

9. mukushla

i gotta go...good night from eastern hemisphere :) think about it.

10. help_needed

ok tahnks!
