I HAVE A PROBLEM WITH A COUPLE OF INTEGRALS.
THERE ARE TWO INTEGRALS WHICH I HAVE TO SOLVE SIMULTANEOUSLY.I COULDN'T
DO IT. IF YOU CAN HELP ME (OR SOLVE THEM AND SEND ME) IT WOULD BE GREAT.
THE INTEGRALS ARE dM(r)/dR=4(Pi)R.R.S
& G=CONST(GRAVITATIONAL CONST.)
S=ASSUME IT(DENSITY)
dP/dR=-GM(r).S/R/R M=ASSUME IT(MASS)
R=RADIUS
P=PRESSURE
AFTER THEN I HAVE TO MAKE A GRAPH OF R , M , P , S FOR PROPER S&M VALUES.
THANKS FOR YOUR HELP......
