System of transcendental equations?

  1. Sep 12, 2010 #1
    1. The problem statement, all variables and given/known data

    I need to find theta (0) and with that I can find W but im not sure how to I think im on the right track but im stumped now and apparently theres a tool on calculators to help you with finding theta rather than guessing. Here are the given equations

    0.5TDAsin0=0
    0.866TDA-W=0
    0.5TDAcos0=50

    2. Relevant equations



    3. The attempt at a solution

    So i did equation 1 minus equation 3 to eliminate 0.5T.. which gave me

    sin0-cos0=-50

    Is this the right track? can it even equal -50??

    0=Theta when placed beside sin and cos, not zero.

    You used row operations to simplify the system, which is quite all right, but you forgot about the coefficient that was attached to each equation. ;)
