## anonymous 5 years ago derivate 3t(sint/t-t^2/3)

1. anonymous

$3t*((\sin t)/(t- t ^{2/3}))$ Is this the question?

2. anonymous

i need to find the derivate

3. anonymous

I know, I want to know if I wrote the question correctly.

4. anonymous

yes :=)

5. anonymous

Okay. Its quite trivial, but tedious. Its easy to make mistakes in this. Do you just want the answer to verify your answer or do you need explanation also?

6. anonymous

yes i want the answer please i want to verify if with mine these derivates are driving me crazy

7. anonymous

wait the question is wrong

8. anonymous

okay

9. anonymous

3t((sint/t)-t^2/3))

10. anonymous

3T(sin t divided by t and t^2 divided by 3)

11. anonymous

aite cool

Well. This problem looks alot less tedious than before. Just distribute the 3t and you'll get: 3sin(t) - t^3 When you take its derivative you'll get: 3cos(t) - 3t^2

i got 3cos(T)-9T^2 the 9 from multiplying 3t(t^2/3) dont know ;-(
