Question

integral(1 to 4) (sqrt(t)ln(t))dx

Answer 1

integration by parts :)

Answer 2

\[\int\limits_1^4\sqrt t\ln t\text dx\]
\[=\sqrt t\ln t\int\limits_1^4\text dx\]

Answer 3

or did you mean dt

Answer 4

yes dt
sorry

Answer 5

\[\int_{1}^{4} \sqrt{t} \ \ln{t} \ \text{d}t\]

Answer 6

yes right

Answer 7

well do integration by parts letting\[\text{d}v=\sqrt{t} \ \text{d}t\]\[u=\ln t\]

Answer 8

du?

Answer 9

\[\text{d}u=\frac{1}{t} \text{d}t \]???

Answer 10

do u know integration by parts?

Answer 11

um.. i got \[\frac{ 4 }{ 9 }(4\ln (64)-7)\]

Answer 12

Is this right?

Answer 13

let me check it

Answer 14

thats right :)
