estimate f'(0) if f(x) =sinx, with x in degrees round estimate to four decimal places

OpenStudy (kc_kennylau):

Oh God this question again

OpenStudy (anonymous):

its come up before?

OpenStudy (kc_kennylau):

This question has already been asked in open study, our conclusion was that this question is not well set

OpenStudy (kc_kennylau):

Because cos(0)=1 and the answer should be 1

OpenStudy (kc_kennylau):

But the answer in the end turns out that

OpenStudy (kc_kennylau):

turns out that they want us to approach from the right and stop when it agrees to 4 decimal places

OpenStudy (kc_kennylau):

And yes its come up before

OpenStudy (anonymous):

so how would i solve it?

OpenStudy (kc_kennylau):

Approach from the right and stop when it agrees to 4 decimal places

OpenStudy (kc_kennylau):

this function \(\dfrac{\sin x}x\)

OpenStudy (kc_kennylau):

But I followed the answer's method and I still came up with 1

OpenStudy (kc_kennylau):

Or can you try 0.9999?

OpenStudy (anonymous):

doesn't work

OpenStudy (kc_kennylau):

Yep this question is flawed I can't even get the answer using their method

OpenStudy (kc_kennylau):

Just ignore this question lol

OpenStudy (anonymous):

OpenStudy (anonymous):
