Calculation of Trigonometric Functions

To calculate the values of the trigonometric functions, we can use the following formulas:

1) sin(545): - The sine function calculates the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle. - To calculate sin(545), we need to convert the angle to a reference angle between 0 and 360 degrees. - Since sin(x) = sin(x + 360k) for any integer k, we can subtract multiples of 360 from the angle until we get a value between 0 and 360. - sin(545) is equivalent to sin(545 - 360) = sin(185). - Using a calculator or trigonometric table, we find that sin(185) is approximately -0.9962.

2) cos(945): - The cosine function calculates the ratio of the length of the side adjacent to the angle to the length of the hypotenuse in a right triangle. - To calculate cos(945), we need to convert the angle to a reference angle between 0 and 360 degrees. - Since cos(x) = cos(x + 360k) for any integer k, we can subtract multiples of 360 from the angle until we get a value between 0 and 360. - cos(945) is equivalent to cos(945 - 360) = cos(585). - Using a calculator or trigonometric table, we find that cos(585) is approximately -0.9962.

3) tan(1545): - The tangent function calculates the ratio of the sine of the angle to the cosine of the angle. - To calculate tan(1545), we need to convert the angle to a reference angle between 0 and 360 degrees. - Since tan(x) = tan(x + 180k) for any integer k, we can add or subtract multiples of 180 from the angle until we get a value between 0 and 360. - tan(1545) is equivalent to tan(1545 - 180) = tan(1365). - Using a calculator or trigonometric table, we find that tan(1365) is approximately -0.9962.

4) cot(525): - The cotangent function calculates the reciprocal of the tangent function. - To calculate cot(525), we need to convert the angle to a reference angle between 0 and 360 degrees. - Since cot(x) = cot(x + 180k) for any integer k, we can add or subtract multiples of 180 from the angle until we get a value between 0 and 360. - cot(525) is equivalent to cot(525 - 180) = cot(345). - Using a calculator or trigonometric table, we find that cot(345) is approximately -0.9962.

Therefore, the approximate values of the given trigonometric functions are: 1) sin(545) ≈ -0.9962 2) cos(945) ≈ -0.9962 3) tan(1545) ≈ -0.9962 4) cot(525) ≈ -0.9962

Please note that the values provided are approximate and rounded for simplicity.
