Column 1 Column 2
sec theta - cos theta
tan theta sin theta
Question: how do you get column 1 to be the same as column 2 ?? using the eight fundamental identities

  • Trig -

    Now we are cooking

    working on the left

    1/cos t - cos t

    1/cos t -cos^2 t/cos t

    (1 - cos^2 t)/cos t

    sin^2 t/cos t

    (sin t/cos t) sin t

    tan t sin t
    which is on the right
