Give an example of a function that is integrable on the interval [-1,1], but not continuous on [-1,1]. explain.
1 answer:
With an absolute value somewhere in the formula, you can create a discontinuous function.
how about f(x) = |x|/x
It jumps from -1 to +1 at x=0, yet it can be integrated on [-1,1]. The surface is 2.

n = 20
d = 6
a = 4
L = a + (n - 1)*d
L = 4 + (20 - 1)*6
L = 4 + 19*6
L = 118
Sum = (a + L)*n/2
Sum = (4 + 118) * 20/2
Sum = 122 * 10
Sum = 1220
M<J = m<N ( alternate angles)
m<K = m<M ( alternate angles)
so the third angles must also be equal ( total 180 degrees in each triangle)
Therefor the triangles are similar
