Sorry, but forum rules do not permit posting equations as images. You need to use the PF LaTeX feature to post your actual equations. Help on that feature can be found here:

Please start a new thread with the homework template filled out correctly using LaTeX. This thread is closed.

Note to other participants whose posts have also been deleted: using the PF LaTeX feature is a requirement for everybody. Please see the help page I linked to. Using it also has the nice side effect of removing any ambiguity about what symbols you intended to use.
