**Problem e: Limit of a Difference Quotient**
\[
\lim_{x \to a} \frac{\sec(x) - \sec(a)}{x - a}
\]
This problem involves finding the limit of a difference quotient, which is a fundamental concept in calculus used to determine the instantaneous rate of change of a function. Here, it specifically examines the secant function, \(\sec(x)\), which is the reciprocal of the cosine function.
**Problem f: Limit of a Sum as \( n \to \infty \)**
\[
\lim_{n \to \infty} \sum_{i=1}^{n} \left( 5 + \frac{2i}{n} \right)^{10} \frac{2}{n}
\]
This represents the limit of a Riemann sum, often used to approximate the area under a curve as the number of intervals (n) approaches infinity. The expression \(\left( 5 + \frac{2i}{n} \right)^{10}\) is evaluated across subintervals, and \(\frac{2}{n}\) represents the width of each subinterval. This is a common method for converting an integral into a sum for computational purposes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Feddd6036-05ca-49ad-a1c3-fdec7d647876%2F8a88a65b-424a-4dd5-a0e2-f19877d243a7%2Fc4fp1q86_processed.png&w=3840&q=75)
