Find the values of Q in degrees and radians without the aid of a calculator.

a) cotQ = sqrt 3 / 3
b) secQ = sqrt2

  • Pre-Cal - ,

    a) tan Q = sqrt3
    What angle has that tangent? You should know. Consider a 30-60-90 right triangle.
    b) cos Q = 1/sqrt2 = 0.707
    sin Q would be the same.
    What is Q when tanQ = 1?
