If a question asks you to find a higherorder derivative, then we should differentiate the function a few times and look for a pattern. Of course, you should remember all the derivative techniques such as the power rule, product rule, quotient rule, and chain rule.

0:00 Q1 higherorder derivative of ln(x)
5:23 Q2 higherorder derivative of cos(x)
9:17 Q3 higherorder derivative of sin(2x)
13:02 Q4 higherorder derivative of sqrt(e^x)
15:36 Q5 higherorder derivative of x*e^x
