Homework Help: Latex problems

  1. Feb 1, 2010 #1
    hi. not sure if this is the right forum.
    i have latex code that i'm trying to get to print but it's giving me 28 errors and i can't find any of them


    i've got it to display nice but i'm still getting 28 errors when i run and they're all apparently related to missing brackets and stuff but i just can't find them
    here's my code:

    \begin{align}
    \theta^0{}_1 &= L^{-2}e^{-2a} \left \{ \left( a'' - \ddot{a} \right) \omega^0 \wedge \omega^1 - \left( \star \left[ P_{\text{sym}}, U_{\text{sym}} \right] \right) \omega^2 \wedge \omega^3 \right \} \\
    \theta_0 &= L^{-2}e^{-2a} \biggl\{ \biggl( \dot{a} P_{\text{sym}} + a' U_{\text{sym}} - \dot{P}_{\text{sym}} - {P_{\text{sym}}}^2 + \left( \star P \right) \left[ \epsilon, P \right] \biggr) \omega^0 \right \\ \nonumber &+ \biggl( a'P_{\text{sym}} + \dot{a} U_{\text{sym}} - {P_{\text{sym}}}'-P_{\text{sym}}U_{\text{sym}} + \left( \star U \right) \left[ \epsilon, P \right] \biggr) \omega^1 \biggr\} \wedge \omega \\
    \theta_1 &= L^{-2}e^{-2a} \biggl\{ \biggl( a' U_{\text{sym}} + \dot{a} P_{\text{sym}} - {U_{\text{sym}}}' - {U_{\text{sym}}}^2 + \left( \star \right) \left[ \epsilon, U \right] \biggr) \omega^1 \right \\ \nonumber &+ \left \biggl( \dot{a} U_{\text{sym}} + a'P_{\text{sym}} - \dot{U}_{\text{sym}} - U_{\text{sym}}P_{\text{sym}} + \left( \star P \right) \left[ \epsilon, U \right] \biggr) \omega^0 \biggr\} \wedge \omega \\
    \theta &= L^{-2}e^{-2a} \left( \left[ U, P \right]_{\text{asym}} \omega^0 \wedge \omega^1 + \left( \text{det} U_{\text{sym}} - \text{det} P_{\text{sym}} \right) \omega \wedge \omega \right)
    \end{align}

    and the display:

    [itex]\begin{align}
    \theta^0{}_1 &= L^{-2}e^{-2a} \left \{ \left( a'' - \ddot{a} \right) \omega^0 \wedge \omega^1 - \left( \star \left[ P_{\text{sym}}, U_{\text{sym}} \right] \right) \omega^2 \wedge \omega^3 \right \} \\
    \theta_0 &= L^{-2}e^{-2a} \biggl\{ \biggl( \dot{a} P_{\text{sym}} + a' U_{\text{sym}} - \dot{P}_{\text{sym}} - {P_{\text{sym}}}^2 + \left( \star P \right) \left[ \epsilon, P \right] \biggr) \omega^0 \right \\ \nonumber &+ \biggl( a'P_{\text{sym}} + \dot{a} U_{\text{sym}} - {P_{\text{sym}}}'-P_{\text{sym}}U_{\text{sym}} + \left( \star U \right) \left[ \epsilon, P \right] \biggr) \omega^1 \biggr\} \wedge \omega \\
    \theta_1 &= L^{-2}e^{-2a} \biggl\{ \biggl( a' U_{\text{sym}} + \dot{a} P_{\text{sym}} - {U_{\text{sym}}}' - {U_{\text{sym}}}^2 + \left( \star \right) \left[ \epsilon, U \right] \biggr) \omega^1 \right \\ \nonumber &+ \left \biggl( \dot{a} U_{\text{sym}} + a'P_{\text{sym}} - \dot{U}_{\text{sym}} - U_{\text{sym}}P_{\text{sym}} + \left( \star P \right) \left[ \epsilon, U \right] \biggr) \omega^0 \biggr\} \wedge \omega \\
    \theta &= L^{-2}e^{-2a} \left( \left[ U, P \right]_{\text{asym}} \omega^0 \wedge \omega^1 + \left( \text{det} U_{\text{sym}} - \text{det} P_{\text{sym}} \right) \omega \wedge \omega \right)
    \end{align}[/itex]
    sort of works here and it definitely does on TeXnicCenter which is what i'm using.

    thanks for any help.

    You cannot write \right when you don't want a delimiter. Instead, use \right. (\right followed by a period).
