State whether true or false: \(\int\log x\,dx=x\log x+x+c\).
Q.1 (B) (ii) State whether true or false: \(\int\log x\,dx=x\log x+x+c\).
Q.1 (B) (ii) State whether true or false: \(\int\log x\,dx=x\log x+x+c\).
Best answer
Answer: False
Integrating by parts, \(\int\log x\cdot1\,dx=x\log x-\int\frac{1}{x}\cdot x\,dx=x\log x-x+c\). The sign of \(x\) in the given statement is wrong.
