find the primary solutions. 4cos^2x-3=0 and tanx-tan^2x=0.

  • trig -

    4cos^2x-3=0
    cos^2 x = 3/4
    cos x = ± √3/2

    If by primary solutions you mean 0≤ x ≤ 360
    then x = 30°, 150°, 210°, 330°
    in radians: π/6, 5π/6, 7π/6,11π/6

    the second one:
    tanx(1-tanx) = 0
    tanx = 0, or tanx = 1

    let me know what you got for x

    How do I solve this? tan^2x= 2tanxsinx My work so far: tan^2x - 2tanxsinx=0 tanx(tanx - 2sinx)=0 Then the solutions are: TanX=0 and sinX/cosX = 2 sin X Divide through by sinX: we have to check this later to see if allowed (ie sinX
