#1) what is the area of the region that lies under y= xe^(-x^2),

over 0 greater than or equal to x less than or equal to 3

#2) What is the graph of definite integral (lnx)^2 dx between 1 and e?

3#) what is the antiderivative of ln2?

#1) Not very clear to me (Thinking)

#2) You can integrate lnē(x) by parts using u'(x)=1 and v(x)=lnē(x)

3#) ln(2) being a constant, its antiderivative is ln(2) x + constant
