If CSC X = 4 in the quadrant 1, what is COS X?

  • Trig -

    cos(x)=(4^2-1^2)^(1/2). If your csc=4, then build your right triangle and if csc(x) is hyp/opposite, then you should get what i have put above. Hope this helps

  • Trig -

    if cscx = 4, sinx = 1/4

    cos^2 = 1 - sin^2 = 15/16
    cosx = √15 / 4

  • Trig -

    my mistake, I forgot to put the 4 underneath the sq root of 15
