Question

evaluate the integral a=1 b=2 f(x)= 3/t^4

Answer 1

thing you mean f(t) = 3/t^4

Answer 2

\[\int\limits_{1}^{2} \frac{3}{t^4} dt \]

Answer 3

\[= 3 \int\limits_{1}^{2} t^{-4} dt\]

Answer 4

\[= 3( \frac{t^{-3}}{-3} ) \]

Answer 5

between the limits

Answer 6

\[- [ \frac{1}{t^3}] \] between 2 and 1

Answer 7

\[= - ( [ 1/8] - [1/4] ) = (1/8)\]

Answer 8

1/8
