Integral Question: This is trignometric substitution right?

OpenStudy (lalaly):

ok?

OpenStudy (anonymous):

\[\int\limits_{?}^{?} 4-x/\sqrt{4-x^2}\]

OpenStudy (anonymous):

yes

OpenStudy (lalaly):

yeh trig substitution

OpenStudy (saifoo.khan):

lulu

OpenStudy (anonymous):

my teacher posted it in the the first test section for my final exam study sheet but it doesn't look like a test 1 question

OpenStudy (lalaly):

Saifoooooo xD

OpenStudy (saifoo.khan):

:D

OpenStudy (dumbcow):

No you don't need trig substitution u = 4-x^2 du = -2x dx --> dx = -du/2x the x's cancel, leaving \[-\frac{1}{2}\int\limits_{}^{}4 - \frac{1}{\sqrt{u}} du\]

OpenStudy (dumbcow):

wait actually it should be \[\int\limits_{}^{}4 + \frac{1}{2\sqrt{u}}du\]
