Answer 2

=ln(secx+ tanx) +c

Answer 3

how to get ln(secx+ tanx) +c ??? please

Answer 4

\[\int\limits_{}^{}\sec(x) \cdot \frac{\sec(x)+\tan(x)}{\sec(x)+\tan(x)} dx\]
use a substutition

Answer 5

let u=bottom
du=the whole top part
-----
=ln|u|+C=ln|bottom|+C

Answer 6

bottom=sec(x)+tan(x)
the whole top part=sec(x)(sec(x)+tan(x)) dx

Answer 7

???

Answer 8

question again????
modulus of 13^2^2011 division 16
plissss plisss :(
