Evaluate sin(-60 degrees ) Step 1. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. ... The exact value of is .Trigonometry. Find the Exact Value sin (240 degrees ) sin(240°) sin ( 240 °) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because sine is negative in the third quadrant. −sin(60) - sin ( 60)From the trigonometric formula, sin (90° – a) = cos a. You can now find the value of cos 60. You can write the above formula as: Sin (90° – 60°) = cos 60°. This gives you sin 30° = cos 60°... (2) Since the value of sin 30 is ½, Substitute this value in (2). Doing so, you get,

The 30°-60°-90° sides are "as usual", namely 1, 2 and √3. From the two 45°-45°-90° triangles, it is quite easy to see that x is √3 √2 and y is 1 √2 from which we can read off the sines and cosines of 15° and 75°. However we will get some nicer numbers on the triangles if we expand all sides by a factor of √2.This video works to determine the exact values for the sin(30), cos(30), tan(30), sin(60), cos(60), and tan(60) using an equilateral triangle and the accompa...sin(60°)−cos(60°)= 23 −1 Explanation: The exact values of cos(60°) and sin(60°) ...

The exact value of Sin 180 Degrees is 0. Sin 180 Degrees is written as sin (180° × π/180°) in radians, i.e. sin (π) or sin (3.141592. . .). Trigonometry is a branch of Mathematics that deals with the length, height, and angles of a right-angled triangle. ... sin 60° sin π/3: √3/2:Then basic trigonometry tells us: sin θ = b a2+b2√ sin θ = b a 2 + b 2 and cos θ = a a2+b2√ cos θ = a a 2 + b 2. From this, cos θ = 2 5√ 5 cos θ = 2 5 5, but since we know it's less than 0 0, it is simply the negative, so cos θ = −2 5√ 5 cos θ = − 2 5 5.Method 2. By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. As given, sin (90° +30°) = cos 30°. It means that sin 120° = cos 30°. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2. Explanation: For sin 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since sine function is positive in the second quadrant, thus sin 120° value = √3/2 or 0.8660254. . . Since the sine function is a periodic function, we can represent sin 120° as, sin 120 degrees = sin (120° + n × 360°), n ∈ Z. \displaystyle{\sin{{\left({60}°\right)}}}-{\cos{{\left({60}°\right)}}}=\frac{{\sqrt{{3}}-{1}}}{{2}} Explanation: The exact values of \displaystyle{\cos{{\left({60 ...
On the trig unit circle: sin 120 = sin (180 - 60) = sin 60 = sqrt3/2. Trigonometry . Science Anatomy & Physiology Astronomy Astrophysics ... What is the value of #sin -45^@#?The value of sin 270 degrees is -1. Sin 270 degrees can also be expressed using the equivalent of the given angle (270 degrees) in radians (4.71238 . . .). ⇒ 270 degrees = 270° × (π/180°) rad = 3π/2 or 4.7123 . . . For sin 270 degrees, the angle 270° lies on the negative y-axis. Thus, sin 270° value = -1.To convert degrees to radians, multiply by π 180° π 180 °, since a full circle is 360° 360 ° or 2π 2 π radians. The exact value of sin(60) sin ( 60) is √3 2 3 2. Multiply √3 2 ⋅ π 180 3 2 ⋅ π 180. ….

How to find Sin Cos Tan Values? To remember the trigonometric values given in the above table, follow the below steps: First divide the numbers 0,1,2,3, and 4 by 4 and then take the positive roots of all those numbers. Hence, we get the values for sine ratios,i.e., 0, ½, 1/√2, √3/2, and 1 for angles 0°, 30°, 45°, 60° and 90°.All you need to remember about this table is the arrangement of rows and columns i.e. angles are placed in columns and trigonometric functions at the rows. So draw a table and start with the sine values. Step 1 (red): In each of the empty cells for sine of 0,30,45,60 and 90 write (0,1,2,3,4) respectively.
