If tanx = 2/3 tany = 1/2
then tan(x-y) = ??

a.7/4
b.7/6
c.1/8
d.8/6

which answer is correct ??

  • Trig -

    tan(a-b) = [ tan a - tan b)/(1 + tan a tan b)

    You better learn those trig identities.

  • Trig -

    The answer is 1/8
    Is that correct Damon ?

  • Trig -

    Yes, correct

  • mathameticks -

    (a) 7/4
