Homework Statement
dy/dx(x^n) = nx^(n-1)
∫(x^n)dx = (x^(n+1))/(n+1) + C (for n ≠ -1)
Q1ow do you know that x^n is the only function which has the derivative of nx^(n-1)?
and (x^(n+1))/(n+1) + C are the only primitive function of x^n?
Q2:∫(x^(-1))dx = ln|x| + C
We cannot use the power rule of integration in x^n when n = -1 as the result is undefined.
but we have the above formula to find the primitive function of x^-1
Is there any relationship between:
(x^(n+1))/(n+1) + C and ln|x| + C ?
Thx :)
