WebApr 7, 2024 · Now that we know how to do these, the next two should be fairly simple: The only value on the interval π to 0 that has a cos (or x) value of √2 2 is π 4, so the answer is π 4. The only value on the interal π to 0 that has a cos (or x) value of − 1 2 is 2 π 3, so the answer is 2π 3. This type of lesson is much better explained visually ...

Find the sum of sin^-1(1/√2) + sin^-1((√2 - 1)/√6) + sin^-1((√3 - √2…
WebFor example, tan 30° = tan 210° but the same is not true for cos 30° and cos 210°. You can refer to the trigonometry formulas given below to verify the periodicity of sine and cosine functions in different quadrants. First Quadrant: sin (π/2 – θ) = cos θ. cos (π/2 – θ) = sin θ. sin (2π + θ) = sin θ. WebSep 23, 2015 · Explanation: as − √3 2 isN egative. and cos function is negative in 2nd and 3rd quadrant. − √3 2 = cos(π− π 6) or cos(π+ π 6) as arccosx range is in [0,π]cos(π + π 6) is ruled out. − √3 2 = cos(π− π 6) ⇒ − √3 2 = arccoscos(π − π 3) = π− π 6 = 5 π 6 radians = 5 6 ⋅ 180o = 150o.

We know that, Sin 30° = BD/AB = a/2a = 1 / 2. Therefore, Sin 30 degree equals to the fractional value of 1/ 2. Sin 30° = 1 / 2. Therefore, sin 30 value is 1/2. In the same way, we can derive other values of sin degrees like 0°, 30°, 45°, 60°, 90°,180°, 270° and 360°. how to unlock number lock
