f(x)=12x/sinx+cosx
find f'(-pie)
thats not the answer
Please see your prior post.
If you know the answer, why are you asking?
Also, it would help if you posted the answer you think it is, then a tutor might have a better understanding of what is maybe being misunderstood.
I think I see your problem. In prior posts
you had,
f(x)=12x/sinx+cosx
find f(-pie)
Now, you have f', the derivative.
f'(-pie).
Which is it?
im not saying it like that and i did the work but its not right answer the computer says when i put the answer in it says incorrect.
this is what i did:
12(-pi)/(0+(-1))
= 12pi
but its not right i don't know why?
f'(-pie) that's what i need to find
Did you read my post just above yours?
In your first post asking this question, the one that MathMate answered 12pi,
you had the problem as,
f(x)=12x/sinx+cosx
find f(-pie)
Now you have,
f(x)=12x/sinx+cosx
find f'(-pie)
f and f' are different.
f' is the derivative.
Which is it?
yes i need to find the derivative of f'(-pie)
this is the equation:
f(x)=12x/(sinx+cosx)
and i need to find:
f'(-pie)
can you help me!!
Is the answer -12 - 12pi?
I did this real quick, and don't have time to post all the work or to double check my work, so I'm not positive this is correct.
I can look at this more in the morning or maybe another tutor will answer.
