in the attatch file there is the dd function.
what i want to know is: when x doesn't equal 0 the function equals 0 and the inegral is the integral of the number 0 which is any constant therefore i think the integral should be equal 0.
can someone show me how this integral equals 1?
for your convinience here is the website that the gif was taken from:

another thing that i don't understand is how can you restrict an integral with b and a when it equals a constant for example int(b-a):0dx. the anti derevative of 0 is some C now how can you put into a number numbers that propety is only for variables.
