definite integral

Sketch the region whose area is given by the definite integral. (Do this on paper. Your instructor may ask you to turn in this graph.) Then use a geometric formula to evaluate the integral.




so here what i did was
separate(1/ and the x
so i graphed y=x
and then i got that at point 5, y =5

so then i found the area of the triangle

(5)(5)(.5)= 12.5
the multiply by the (1/
so i got

1.5625 or 25/16

is this correct?

Re: definite integral

Perhaps you should sketch from x = 0 to x = 5.

That is why I made my suggestion. Your result is correct.
