Answer 2

Calculation 1: tg 720 + sin 540 - ctg 135

To solve this calculation, we can break it down into smaller parts and evaluate each part separately.

1. tg 720: - According to the trigonometric function, the tangent of 720 degrees is equal to the tangent of 360 degrees, which is equal to the tangent of 0 degrees, which is 0. - Therefore, tg 720 = 0.

2. sin 540: - According to the trigonometric function, the sine of 540 degrees is equal to the sine of 180 degrees, which is 0. - Therefore, sin 540 = 0.

3. ctg 135: - According to the trigonometric function, the cotangent of 135 degrees is equal to the cotangent of (90 + 45) degrees, which is equal to the negative tangent of 45 degrees, which is -1. - Therefore, ctg 135 = -1.

Now, let's substitute these values back into the original calculation:

tg 720 + sin 540 - ctg 135 = 0 + 0 - (-1) = 0 + 0 + 1 = 1.

Therefore, the result of tg 720 + sin 540 - ctg 135 is 1.
