In summary, for kindergarden homework, the person is asked to find the derivative of f(x)=S t^3 dt with respect to x. The initial response is t^3, but it is incorrect. The correct method is to first find the indefinite integral of t^3 dt, evaluate it from t=x to t=10, and then differentiate the resulting expression with respect to x. The correct answer is 0-x^3. The person thanks Warren for their fast and helpful response.

HI people, this will be kindergarden homework for you guys. PLease help! THANKS ALOT!

S=integral sign

10
S t^3 dt=f(x)
x

f'(x)=?
I say f'(x)=t^3, but it's not correct. WHY?

First, find the indefinite integral of t3 dt, then evaluate it from t=x to t=10. Only after you've completed that can you differentiate the resultant expression with respect to x.

so the indefinite integral of t^3 dt is t^4/4

then evaluate it from t=x to t=10

10^4/4-x^4/4

then differentiate this expression

0-x^3

it's correct!... I am dumb THANX ALOT fOR The fAsT repLY !
