herraotic said:Let (an) be a sequence of positive real numbers, decreasing and the sum of whose terms is infinite. Prove that the series whose general term is min(an, 1/n) is also divergent.
I'm sorry but I'm no where with it. Could someone tell me if this is too difficult?
Thanks!
Calculus is a branch of mathematics that deals with the study of continuous change and is used to analyze and model various phenomena in fields such as physics, engineering, and economics.
A calculus question can be considered tricky if it involves complex concepts, multiple steps, or requires creative problem-solving techniques to arrive at the solution.
To approach a tricky calculus question, it is important to first understand the underlying concepts and principles involved. Then, break down the question into smaller, more manageable parts and use appropriate techniques and formulas to solve each part. Finally, carefully analyze and interpret the results to arrive at the final solution.
Some common challenges when solving tricky calculus questions include understanding the problem, choosing the right approach, correctly applying formulas and techniques, and avoiding calculation errors. It is also important to check the solution for reasonableness and accuracy.
Some tips for successfully solving tricky calculus questions include practicing regularly, understanding the underlying concepts and principles, breaking down the problem into smaller parts, using visual aids and diagrams, and checking your work for errors. It can also be helpful to seek assistance from a teacher or tutor if needed.
