    Default Solving Physical Problems

    This thread is for anyone to post any physical science problem and to find the ways to solve it.

    I would like to start my question first.

    Prove that product of an even function and an odd function is an odd function.

    This is a problem on my test this morning. I finished it, but I just realized that I did it wrong. Please help me to solve this. Thank you!

    1st Version:
    Anyone who teaches me one word - even half a word - is still my teacher.
    2nd Version:
    Even he who teaches me the smallest bit can still be called my teacher

    Please correct my grammar as you see fit. Much appreciated!

    At first, tell me what is an odd function or an even function.
    However, you can imagine that multiplying an even integer number by an odd number you can see another even number.
    The matter is similar to the product of two integer numbers
