If you put the indefinite integral into Y1 for a graph and then place as many numbers in L1(The more the better) and then go into "VARS", "Y-VARS", "FUNCTION" and select "Y1". Then use "Y1(L1)sto>L2" to find all Y values of the indefinite integral and use a regression command to give the equation for the Indefinite Integral.EX:Y1=∫0x(3x^2)dx
L1={−10,−9,−8,−7,−6,−5,−4,−3,−2,−1,0,1,2,3,4,5,6,7,8,9,10}
Y1(L1)→L2
CubicReg using L1 as Xlist and L2 as Ylist
y=ax^3+bx^2+cx+da=1b=0c=0d=0
y=x3
