Trig/Algebra Question

  1. Aug 26, 2013 #1
    Hello, All,

    I am unclear what my oversight is on this one -- supposed to be getting -√2 as the answer on these practice worksheets, however I keep getting -√2/2. Where is the factor? Thank you for your guidance

    (cos^2 ∏) / (sin 5∏/4)

    (-1)^2 / (-√2/2)

    (1) * (-2/√2)

    (-2/√2) * (√2/√2)

    (-√2/2)

    ?

    -mk

    In simplifying this, what is the final numerator: (-2/√2) * (√2/√2)

    Try re-arranging this as

    -2/(√2 √2) * (√2)
