Sin 135 degrees.
For sin 45 degrees, the angle 45° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 45° value = 1/√2 or 0.7071067. . . Since the sine function is a periodic function, we can represent sin 45° as, sin 45 degrees = sin (45° + n × 360°), n ∈ Z. ⇒ sin 45° = sin 405° = sin 765 ...
Notice also that sin θ = cos (π 2 − θ), sin θ = cos (π 2 − θ), which is opposite over hypotenuse. Thus, when two angles are complementary, we can say that the sine of θ θ equals the cofunction of the complement of θ. θ. Similarly, tangent and cotangent are cofunctions, and secant and cosecant are cofunctions.Sin 135 degrees = [tex]-\frac{\sqrt{2}}{2}$[/tex] Sin 150 degrees = 1/2; Sin 180 degrees = 0; ... in equation cos(2x) = 0, the x values that satisfy this equation are x = 45 degrees and x = 135 degrees, as these are where cosine of an angle is zero within the specified range of 0 degrees to 180 degrees. So, the answer is x = 45 degrees and x ...In this case, if we know that ∠P measures 27° and ∠R measures 135°, we can use the Law of Sines to find the length of side P. The Law of Sines states that the ratio of a side length to the sine of its opposite angle is constant. Let's calculate: Sin∠P / p = Sin∠R / R. Sin(27)° / 9.5 = Sin(135)° / P. Solving for P:cos (135) cos ( 135) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

In trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin(45) = 0.707. The angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator: sin(135) = 0.707The expression 1 - cos(135) / sin(135) can be rewritten using half-angle identities to yield 1 - sqrt[2/2], or 1 - sqrt(0), which simplifies to simply 1. Explanation: The half-angle formulas are expressions for the sine, cosine, and tangent of half of a given angle in terms of the sine, cosine, or tangent (respectively) of the given angle. They ...Since one degree is equal to 0.017453 radians, you can use this simple formula to convert: radians = degrees × 0.017453.
