Homework Statement
1)Evaluate the definite integral using FTC:
[tex] \int_1^4 \left( \frac{d}{dt} \sqrt{4+3t^4} \right)dt [/tex]
2)Evaluate the definite integral:
[tex] \int_{-2}^6 f(x)dx [/tex]
f(x)=
{x if x<1}
{1/x if x>=1}
Homework Equations
The Attempt at a Solution
Having trouble getting the anti-derivative it seems...
1)[tex] \int_1^4 \sqrt{4} + \int_1^4 \sqrt{3t^4} [/tex]
[tex] 2\int_1^4 1 + \sqrt{3} \int_1^4 t^2 [/tex]
[tex] 2x + \sqrt{3} \frac {t^3}{3} [/tex]
2)[tex] \int_{-2}^0 x + \int_1^6 \frac {1}{x} [/tex]
[tex] \int_{-2}^0 \frac {1}{2}x^2 + \int_1^6 \ln \abs{x} [/tex]
Anyways, I hope someone answers :\...took quite some time learning the tex format.
