Calculation of tg 720 + sin 540 - ctg 135

To calculate the value of tg 720 + sin 540 - ctg 135, we can break it down step by step:

1. tg 720: According to the search result snippet tg 720 is equal to tg 360, which is equal to tg 0, and tg 0 is equal to 0.

2. sin 540: According to the search result snippet sin 540 is equal to sin 180, and sin 180 is equal to 0.

3. ctg 135: According to the search result snippet ctg 135 is equal to ctg(90 + 45), which is equal to -tg 45, and -tg 45 is equal to -1.

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

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

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