    If sin(x)=1/5 and x lands in the 2nd quad, find tan x

    1 = opposite 5 =hypotonuse 1^2+x^2=5^2

    but it is -sqrt(24) not sqrt(-24)

    tanx=-sqrt24/-24?

    You're looking for tanx for the triangle?

    Ah, well just remember your ratios, you may have heard of SOH CAH TOA, so tan is opposite/ adjacent |dw:1443834717117:dw|

    \[\tan x = \frac{ 1 }{ -\sqrt{24} }\]

    Yes and tan is o/a so tanx=1 which is the opposite/-sqrt24 which is the adjacent

    then we must rationalize the denominator \[\frac{ 1 }{ -\sqrt24 } * \frac{ -\sqrt24 }{ -\sqrt24 }\]

    Yes! you're right

  19. DarkBlueChocobo

    so we would then get \[\frac{ -\sqrt24 }{ 24 }\]
