Science & Mathematics - 15 January 2007

I have been open minded to the possibility for a long time. Why not. But some of the programs that I have seen on T.V. in the last year or so has made me a little uneasy. On UFO files the one about the black box recordings is scary. Some of these sightings were so long ago that there could not have been anything here on earth to compare to what has been seen. Also the USO programs are compelling too. I think that they are out there. There has been more and more info released for public viewing. Are we getting close to an "event"?

Calculus: Area problem?

Find the area in the first quadrant bounded by the arc of the circle described by the polar equation r=2sin(theta)+4cos(theta).
okay i would use the formula dA=r^2 d(theta). Thats what i used is this correct? and when i use this i get: 4sin^2(theta)+16cos(theta)sin(theta)+16cos^2 (theta). The next step would be to integrate right? But when I Integrate this... is there a way i can put the 4 from 4sin^2 (theta) to the left of the integration sign. like in an example r^2/2 the 1/2 is put to the left of the integration symbol and r^2 is integrated (is this making sense to whoever is reading this). well any way is there a way to put the whole numbers like the 4,16,16 to the left of the integration? if not maybe someone can help me do it there way? please i really need this question. please show some steps. i just really want to understand how to be able to integrate!! thanks i know that was long!! i really appreciate everyone's response!!!!=D
