Answer 3

Sure, I can help you with that trigonometric expression. To calculate the value of sin(34°) - sin(86°), you can use a calculator or trigonometric identities.

Let's break it down step-by-step:

Step 1: Convert the angles from degrees to radians (since trigonometric functions usually work with radians):

• 34° in radians is (34 * π) / 180 ≈ 0.59341195 radians.
• 86° in radians is (86 * π) / 180 ≈ 1.49904667 radians.

Step 2: Calculate the individual sine values:

• sin(34°) ≈ sin(0.59341195 radians).
• sin(86°) ≈ sin(1.49904667 radians).

Step 3: Use a calculator or a math library to find the approximated values of the sines:

• sin(34°) ≈ 0.559192903
• sin(86°) ≈ 0.992709874

Step 4: Subtract sin(86°) from sin(34°):

• sin(34°) - sin(86°) ≈ 0.559192903 - 0.992709874 ≈ -0.433516971

So, the result is approximately -0.4335 (rounded to four decimal places).
