• Subtraction

• Multiplication

What is the result of differentiating cos(ax) using the chain rule?

• -a cos(ax)

• a cos(ax)

• -a sin(ax)

• a sin(ax)

What is the purpose of the table of standard integrals provided in exams?

• To replace the need for learning integrals

• To provide a quick reference for common integrals

• To test students' memory

• To confuse students

Why is it not advisable to rely solely on the table of standard integrals during exams?

• They are too complex to use

• The tables are often incorrect

• They are not allowed in exams

• Relying on them can lead to errors if the results are not well understood

What is a limitation of dividing by functions of x when using the reverse chain rule?

• It simplifies the equation

• It can lead to incorrect results

• It makes calculations faster

• It is always allowed

What method is introduced to handle complex functions that cannot be divided by x?

• Long division

• Partial fractions

• Substitution

• Integration by parts

What is the expected outcome when differentiating a function and then anti-differentiating it?

• The function is halved

• The function becomes zero

• The original function is restored

• The function doubles

What is the derivative of tan(ax) according to the discussion?

• a sec^2(ax)

• sec^2(ax)

• a tan(ax)

• a cot(ax)

What is the general advice given about using the table of standard integrals?

• Ignore it completely

• Use it as the primary source of information

• Memorize all entries

• Use it as a safety net but understand the results
