Answer 2

Calculating the Expression

To calculate the given expression, we can follow these steps:

1. Calculate the trigonometric values for 45 degrees and 60 degrees. 2. Substitute these values into the given expression and perform the arithmetic operations.

Let's proceed with these steps.

Trigonometric Values

The trigonometric values for 45 degrees and 60 degrees are as follows: - cos(45) = 0.7071 - sin(45) = 0.7071 - ctg(60) = 1.7321 - tg(60) = 1.7321

Substituting Values and Calculating

Now, let's substitute these values into the given expression and calculate it: 4 * cos(45) * ctg(60) * tg(60) - 3 * sin(45)

= 4 * 0.7071 * 1.7321 * 1.7321 - 3 * 0.7071 = 4 * 0.7071 * 3 - 3 * 0.7071 = 8.4853 - 2.1213 = 6.364

Final Result

The value of the given expression 4cos45*ctg60*tg60-3sin45 is 6.364.
