How can I express sin(37°) * sin(53°) * tan(37°) * tan(53° as a fraction?

To find the value of sin(37°) * sin(53°) * tan(37°) * tan(53°), we can make use of some trigonometric identities and properties.

First, let’s recall that:

  • sin(53°) can be expressed as sin(90° – 37°) = cos(37°)
  • tan(53°) can be expressed as tan(90° – 37°) = cot(37°)

Now, substituting these into our expression:

sin(37°) * sin(53°) * tan(37°) * tan(53° becomes:

sin(37°) * cos(37°) * tan(37°) * cot(37°)

Since tan(37°) = sin(37°)/cos(37°) and cot(37°) = cos(37°)/sin(37°), we find that:

  • tan(37°) * cot(37°) = 1

This simplifies our expression to:

sin(37°) * cos(37°)

Using the double angle identity, we can further rewrite:

sin(37°) * cos(37°) = (1/2) * sin(2 * 37°) = (1/2) * sin(74°)

This is our expression in terms of sin(74°). However, if we’re seeking a numeric result, we can use the approximation:

sin(74°) ≈ 0.9613

Therefore:

sin(37°) * sin(53°) * tan(37°) * tan(53° ≈ (1/2) * 0.9613 ≈ 0.48065

If you would prefer to express this as a fraction, it can be approximated as:

≈ 24/50 = 12/25

Thus, the value of sin(37°) * sin(53°) * tan(37°) * tan(53° in terms of a fraction is approximately 12/25.
