I only know that 't' is odd function and cos(10t) is even function.. so multiply odd with even will give me odd function...
I'm confused is the part on how to solve it mathematically said integration by parts.. haha ...
jpr0 said:If you wanted to use integrate by parts you could probably set the upper and lower limits of integration to some constant [itex]\pm a[/itex]. This symmetric choice of limits will allow you to evaluate the integral by parts, by utilising the symmerty properties of the the now-integrated function to determine what cancellations occur etc. Then in the final step take the limit of [itex]|a|\to\infty[/itex].
Yes, the "even from infinity to -infinity" is wrong. As I said beforeskyflyer54 said:tat true.. if the limit is from A to -A or even from Infinity to -Infinity, the result will be zero. If it is undefined, say like limit from A to B den the answer should not be zero. right ?
This question in the first place was just to solve it to be odd function using mathematical approach. kekez..
Did I said anything wrong ? If yes, pls correct mi. thankz.. heez.
I have absolutely no idea what you mean. You say "What i mean is solve and proof it that the equation is an odd function" but you had just said "we already know that the function is an odd function". Prove what mathematically?skyflyer54 said:From observation, we already know that the function is an odd function, but What i mean is solve and proof it that the equation is an odd function. what i mean is solve and proof it mathematically if possible.

That the integral given doesn't exist?
That the Cauchy Principal Value is 0?
"Difficulty solving the following question" is a common phrase used to describe the struggle or challenge individuals face when trying to find a solution to a problem or answer to a question. It can refer to a range of difficulties, such as lack of understanding, lack of resources, or mental roadblocks.
The reasons for difficulty in solving a question can vary depending on the individual and the specific question. Some common reasons include lack of knowledge or understanding of the topic, inadequate preparation, mental blocks such as anxiety or stress, and limited resources or information.
Improving problem-solving skills requires practice and a systematic approach. Some strategies that can help include breaking down the problem into smaller, more manageable parts, seeking out additional resources or information, collaborating with others, and applying critical thinking and analytical skills.
No, difficulty in solving a question is not necessarily a sign of intelligence. It can be influenced by various factors such as prior knowledge, preparation, and approach. Some individuals may struggle with a particular question or problem, while excelling in other areas.
Overcoming difficulty in solving a question requires persistence, adaptability, and a willingness to try different approaches. It can also be helpful to seek assistance from others, take breaks to clear the mind, and learn from mistakes. Ultimately, finding a solution may require time and effort, but it is achievable with determination and the right strategies.
