The value of sin -1 cos 2 -cos -1 sin 2

WebExplanation: For sin 2 degrees, the angle 2° lies between 0° and 90° (First Quadrant ). Since sine function is positive in the first quadrant, thus sin 2° value = 0.0348994. . . Since the … WebTable 1.9 shows the values of sine and cosine at the major angles in the first quadrant. From this table, we can determine the values of sine and cosine at the corresponding angles in the other quadrants. The values of the other trigonometric functions are calculated easily from the values of and

WebApr 5, 2024 · Let sin-1 (-√3/2) = x and cos-1 (-1/2) = ⇒ sin x = (-√3/ 2) and cos y = -1/2. We know that the range of the principal value branch of sin-1 is (-π/2, π/2) and cos-1 is (0, π). We also know that sin (-π/ 3) = (-√3/ 2) and cos (2π/3) = -1/2. ∴ Value of sin-1 (-√3 /2) + cos-1 (-1/2) = -π/3 + 2π/3 = π/3 WebFinally, the secant function is the reciprocal of the cosine function, and the secant of a negative angle is interpreted as sec(− θ) = 1 cos ( − θ) = 1 cosθ = sec θ. The secant function is therefore even. To sum up, only two of the trigonometric functions, cosine and secant, … WebHow do I get the exact value of cos^2 [1/2 sin-1 (12/13)]? You’ll have to be very careful about how you interpret the expression. Start with what’s in brackets: you need half of the angle whose sine is 12/13. Therefore, you’ll need to use a half-angle trig identity. Further, you’ll have to choose an identity that returns a cosine, so ... iras tax invoice foreign currency
