Sec(x)Sin2(x)
______________________ = 1 - cos(x)
1 + sec(x)
ok using the identity sec(x)=1/cos(x)
I get
1/cos(x) * sin2(x)
__________________________
1 + 1/cos(x)
and that =
sin2(x)/cos(x)
______________________
1 + 1/cos(x)
multiply top and bottom by cos(x)...
Homework Statement

Sec(x)Sin2(x)
______________________ = 1 - cos(x)
1 + sec(x)
Homework Equations
sec(x)=1/cos(x)
sin2(x)=1-cos2(x)

Thanks very helpful.
We kept popping our balloon at launch. We had fast fast acceleration over short distance. Now we have loosened the tension and pulled back further the water balloon.
It is a Project:
I have constructed a waterballon launcher with a group. It looks similar to this, http://www.engr.trinity.edu/images/balloonlaunchers/3balloonlaunch2002.jpg
We are to launch a waterballon an unknown distance between 10-50 meters. We need to determine horizontal range the...
