Answer 3

Solution:

To solve the given expression, let's break it down step by step.

1. Calculate sin(60⁰): - The sine of 60 degrees is equal to √3/2. - Therefore, sin(60⁰) = √3/2 [[1]].

2. Calculate sin(90⁰) and cos(60⁰): - The sine of 90 degrees is equal to 1. - The cosine of 60 degrees is equal to 1/2. - Therefore, sin(90⁰) = 1 and cos(60⁰) = 1/2 [[2]].

3. Substitute the values into the expression: - Now, we can substitute these values into the given expression: 1/3 * sin(60⁰) - 2 * sin(90⁰) * cos(60⁰) + 0.5 * tan(45⁰) = 1/3 * (√3/2) - 2 * 1 * (1/2) + 0.5 * 1 = √3/6 - 1 + 0.5 = √3/6 - 0.5 + 0.5 = √3/6.

4. Final Answer: - Therefore, the value of the given expression 1/3 * sin(60⁰) - 2 * sin(90⁰) * cos(60⁰) + 0.5 * tan(45⁰) is √3/6.
