cot^-1(2tan(cos^-18/17))+tan^-1(2tan(sin^-18/17))=tan^-1300/161

  • math -

    the cos^-18/17 and the sin^-18/17 in your expression don't make sense

    did you mean cos^-1 (18/17) ?
    in that case, that would be undefined, since no angle exists such that cosØ = 18/17
    same thing would be true for the sine part
