    Explanation of photoelectric effect?

    Yo, so we did this a long time ago and I no longer understand. At all. I know that Hertz discovered it through his experiments to measure the speed of EM waves. And yeah, the animations online make little sense :evilfire:

    Series and Sequences - Sum of a series

    Yeah, I think that makes more sense now carrotsticks. The worked solution I was looking through had an error; It had (1) multiplied by (2) not by 2. Thanks all.

    Series and Sequences - Sum of a series

    Hey, I'm not understanding why you have multiplied (1) x 2 in this solution before you solved the simultaneous equations? Thanks for all the responses!

    Series and Sequences - Sum of a series

    Hey, can anybody please help me with this moderately difficult question? If you could do a simple solution with explanations I would be pretty grateful. The 6th term of an arithmetic series is 23 and the sum of the first 10 terms is 210. Find the sum of 20 terms. Thanks

    Difficult 2u integration of exponentials - HELP please

    That x is raised again to (3-1). So x^2 e^x^3-1. I couldn't figure out how to get latex to raise it to another power properly.
