Question

find the centroid of the area of the finite region enclosed by the curve y=x^(2)+1, when x-axis and the line, x=0 and x=3

Answer 1

Just use the formula. The x-coordinate is

∫[0,3] xy dx = ∫[0,3] x^3+x dx
-------------------------------------
∫[0,3] y dx = ∫[0,3] x^2+1 dx

∫[0,3] x^3+x dx
-------------------
∫[0,3] x^2+1 dx

Then do the same for y, using x = √(y-1) since we are in the first quadrant.

Answer 2

but steve i don,t know it dat is why i posted it so that i can gt help from you guys to help me study further

Answer 3

If you do not understand the integral equations, you have a long way to go, namely calculus. Go pick up any 1st-year calculus book, and somewhere in its index you will find how to determine the centroid of a curved area. Google will also help, with many examples, but unless you have picked up come calculus, they will be incomprehensible.

ok thanks steve,i will do just dat
