Given cos(x) = 0.23
We need
to find sin(x), tan(x) , sec(x), and (csc(x).
First, we
know that sec(x) = 1/cos(x).
==> sec(x) = 1/(0.23) =
4.3478.
==> sec(x) =
4.3478.
Now we will use the trigonometric
identities to find sin(x).
We know
that:
sin^2 x + cos^2 x =
1
==> sin(x) =
sqrt(1-cos^2x)
=
sqrt(1-0.23^2)
=
sqrt(0.9471)
=
0.9732
==> sin(x) =
0.9732.
Now we know that csc(x) =
1/sin(x)
==> csc(x) = 1/(0.9732) =
1.0275
==> csc(x) =
1.0275
Now we know that tan(x) = sin(x)/
cos(x).
==> tan(x) = 0.9732/ 0.23 =
4.2313
==> tan(x) =
4.2313
