    1st one use power reducing formula

    2nd 1 over the power reducing formula

    3rd double angle with a sub 3x=2u

    4th 1 over the double angle

    5th \displaystyle \frac{\frac{v^2}{2g}}{\frac{v^2}{g}}=\frac{1}{2} and use trig identities (ones mentioned) to finish it

    Please don't post more than two questions in a thread. Otherwise the thread can get convoluted and difficult to follow. It is better for forum organization and better for you to get your questions answered in a more timely manner if you start new threads as necessary for remaining questions. eg. If you have five questions, post two of them in two threads and start a new thread for the remaining one etc.


    Also, please type the questions out. It is too inconvenient to have to open files and the questions can't be quoted.

    Thread closed.
