How can vectors be added or subtracted? Answer: Vectors are added or subtracted by adding or subtracting their corresponding components.
Explain the method of integration by parts. Answer: Integration by parts is a technique used to integrate products of functions by integrating the derivative of one function and differentiating the other.
What is meant by ‘rationalizing the denominator’? Answer: It involves eliminating the square root or cube root from the denominator of a fraction by multiplying the numerator and the denominator by a suitable term.
How do logarithms simplify multiplication and division? Answer: Logarithms transform multiplication into addition and division into subtraction, simplifying the calculations involving large numbers.
Describe how to find the inverse of a function. Answer: The inverse is found by swapping the x and y values in the original function and solving for the new y.
What is the binomial theorem and its application? Answer: The binomial theorem provides a formula for expanding expressions that are raised to any finite power.
Explain the difference between a permutation and a combination. Answer: Permutations consider the order of the elements, combinations do not.
