just another question about my assessment
The question asks me to evaluate the integral from 0 to 1 of (a+bx+cx^2+dx^3)dx
The answer that i got was a +b/2+ c/3+ d/4 is this right or not???
The last q of the assessment is
a) the area of the region bounded by the curves y=x^2 and y= x+2, between x=0 and x=1 is rotated about the x-axis. find the volume of the generated solid
b) the region in the first quadrant bounded byt the graphs f(x) =1/8 x^3 and
g(x)=2x is rotated aobut the y-axis. find the volume of the solid so formed
Now for this question do i have to find the volumes of the 2 solids separately ie the 2 solids in part a .. then minus one from the other???
