The value of sin 240 degrees can be calculated by constructing an angle of 240° with the x-axis, and then finding the coordinates of the corresponding point (-0.5, -0.866) on the unit circle. The value of sin 240° is equal to the y-coordinate (-0.866). ∴ sin 240° = -0.866.Solve (sin x - cos x) = 0. Ans: 4π and 45π Explanation: Use trig identity: sinx−cosx= 2sin(x− 4π) ... How do you write the trigonometric form into a complex number in standard form 7(cos 0 + isin0) ? 7 or 7+0i Explanation: Begin by evaluating the trigonometric part inside the bracket. Reminder (∣(aa)(cos0 = 1 and sin0 = 0)(aa)∣) ... However, as you might (and should!) remember, sine is a periodic function, so there are multiple numbers that have the same sine value. For example sin(0) = 0, but also sin(π) = 0, sin(2π) = 0, sin(-π) = 0 and sin(-326π) = 0. Therefore, if somebody wants to calculate arcsin(0), the answer can be 0, 2π (360°), or -π (-180°), to name a ...The value of sin 60 degrees, represented as sin 60°, is √3/2, which is approximately 0.866. This trigonometric value signifies the ratio of the length of the side opposite the angle of 60 degrees to the length of the hypotenuse in a right triangle.Lufthansa First Class was an incredible way to fly.

For sin 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 150° value = 1/2 or 0.5. Since the sine function is a periodic function, we can represent sin 150° as, sin 150 degrees = sin (150° + n × 360°), n ∈ Z. ⇒ sin 150° = sin 510° = sin 870 ...Aug 14, 2023 · What is tan 30 using the unit circle? tan 30° = 1/√3. To find this answer on the unit circle, we start by finding the sin and cos values as the y-coordinate and x-coordinate, respectively: sin 30° = 1/2 and cos 30° = √3/2. Now use the formula. Recall that tan 30° = sin 30° / cos 30° = (1/2) / (√3/2) = 1/√3, as claimed. A mortal sin is the most serious type of sin in Christianity. Types of mortal sin include idolatry, adultery, murder and slander. These sins are more serious than venial sins because they go against the most basic teachings of Christianity,\displaystyle{\sin{{\left({60}°\right)}}}-{\cos{{\left({60}°\right)}}}=\frac{{\sqrt{{3}}-{1}}}{{2}} Explanation: The exact values of \displaystyle{\cos{{\left({60 ...Find the Exact Value sin (600) sin(600) sin ( 600) Remove full rotations of 360 360 ° until the angle is between 0 0 ° and 360 360 °. sin(240) sin ( 240) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.
