  1. 1.
    sinØcotØ
    = sinØ(cosØ/sinØ)
    = cosØ

    2.

    ( 1 - sin^2Ø)/cosØ
    = cos^2 Ø/cosØ
    = cosØ

    Can someone please help me do this problem? That would be great! Simplify the expression: sin theta + cos theta * cot theta I'll use A for theta. Cot A = sin A / cos A Therefore: sin A + (cos A * sin A / cos A) = sin A + sin A = 2
