Answer 2

Mathematical Expression: tg 720 + sin 540 - ctg 135

To solve the mathematical expression tg 720 + sin 540 - ctg 135, we can break it down into individual trigonometric functions and evaluate them separately.

1. tg 720: The tangent function of 720 degrees is equal to the tangent of 360 degrees, which is equal to the tangent of 0 degrees, which is 0.

2. sin 540: The sine function of 540 degrees is equal to the sine of 180 degrees, which is 0.

3. ctg 135: The cotangent function 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.

Now, we can substitute these values back into the original expression:

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

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