Sin 240degrees = sin (4/3 × π). Substitute the values into the definition. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. -sin60 = -√3/2.3 ,°042 . sin(240°) = − √3 2 1 sin ( 240 °) = - 3 2 1. By using the value of cosine function relations, we can easily find the value of sin 120 degrees. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest then r^5( cos Ф + i sin Ф )^5 = 243(cos 240 + i sin 240). Notice that 30∘ 30 ∘ is the reference angle for many angles. Formally, the reference angle of an angle in standard position is the angle formed with the closest portion of the x x -axis. In the … We have a double angle identity that says: sin 2 x = 2 sin x cos x We can use it if we consider 2 x = 2 4 0 ∘, ∴ x = 1 2 0 ∘: sin 2 4 0 ∘ = 2 sin 1 2 0 ∘ cos 1 2 0 ∘ ∴ sin 2 4 0 0 = 2 sin ( 9 0 + 3 0 ) cos ( 9 0 + 3 0 ) sin(240°) sin ( 240 °) Find the value using the definition of sine. Make the expression negative because sine is negative in the third … sin (240) = sin (60 + 180) = - sin 60. The value of sin 240 degrees is -0. In general, identifying the reference angle for an angle will help So for the fifth root, get the fifth root of 243, then divide 240 by 5 for your first angle. Trigonometry. You then write the root in the same form as the original, just with your new numbers. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. 本解説では、sin 240° = -0. −sin(60) - … find sin 240Ans: − 2 3Explanation:Trig unit circle -->sin(240)=sin(60+180)=−sin60Trig Table of Special Arcs --> −sin60=− 2 3. For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90°. So there are 5 distinct solutions given by: sin240 = sin (180+60) = -sin60. Calculate the value of the sin of -22. Method 2. Learning math takes practice, lots of practice. So Ф = 48, 120, 192, 264, 336 for 48 ≤ Ф < 360. Find the Exact Value.

Make the expression negative because sine is negative in the third … Learn how to find the value of sin 240 degrees using trigonometric functions, unit circle and identities. Recall that tan 30° = sin 30° / cos 30° = (1/2) / (√3/2) = 1/√3, as claimed.sin(240) sin ( 240) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Divide − √3 2 - 3 2 by 1 1. Choose the proper formula for calculating the reference angle: 0° to 90°: reference angle = angle, 90° to 180°: reference angle = 180° - angle, 180° to 270°: reference angle = angle - 180°, 270° to 360°: reference angle = 360° - angle. cos 45° = sin 45° = 1/√2. cos 30° = sin 60° = √3/2. Exact Form: sin 240 degrees = -√ (3)/2.5 ° To enter an angle in radians, enter sin(-22.
