Some degree values of sine functions and cosine functions are taken from the trigonometry table to find the value of cos 60 degrees. We know that. ⇒90° – 30° = 60° ———– (1) From the trigonometry formula, ⇒sin (90° – a) = cos a. We can find the value of cos 60. We can write it asOct 25, 2015 · Find exact value of sin (105) Ans: (sqrt(2 + sqrt3)/2) sin (105) = sin (15 + 90) = cos 15. First find (cos 15). Call cos 15 = cos x Apply the trig identity: cos 2x = 2cos^2 x - 1. cos 2x = cos (30) = sqrt3/2 = 2cos^2 x - 1 2cos^2 x = 1 + sqrt3/2 = (2 + sqrt3)/2 cos^2 x = (2 + sqrt3)/4 cos x = cos 15 = (sqrt(2 + sqrt3)/2. (since cos 15 is positive) sin (105) = cos (15) = sqrt(2 + sqrt3)/2 ... For cos 210 degrees, the angle 210° lies between 180° and 270° (Third Quadrant ). Since cosine function is negative in the third quadrant, thus cos 210° value = -√ (3)/2 or -0.8660254. . . ⇒ cos 210° = cos 570° = cos 930°, and so on. Note: Since, cosine is an even function, the value of cos (-210°) = cos (210°).This video works to determine the exact value for the sine of 36 degrees algebraically by setting x=36, writing an equation, and solving for sin(x).For more ...

It is known that the values of sines are positive + in the second quadrant. It is also known that, sin ( 180 - x) ° = sin x °. Thus, sin 150 ° = sin 180 - 30 ° = sin 30 ° = 1 2. woofs play and stay wichita ks Explanation: assuming the values are in degrees, sin(45) = sin( π 4) = √2 2. cos(60) = cos( π 3) = 1 2. so. sin(45) + cos(60) = √2 2 + 1 2. = 1 + √2 2.

Note: We could also find the sine of 15 degrees using sine (45° − 30°). sin 75°: Now using the formula for the sine of the sum of 2 angles, sin ( A + B) = sin A cos B + cos A sin B, we can find the sine of (45° + 30°) to give sine of 75 degrees. We now find the sine of 36°, by first finding the cos of 36°. omaha pet licenseprintable alcon rebate form 2023showbiz cinemas homestead reviews Solve for the value of given trigonometric ratio. Given trigonometric ratio: sin 105 0. sin 105 0 can be expressed as, sin 105 ∘ = sin (60 ∘ + 45 ∘) We know that sin ⁡ (A + B) = sin ⁡ A cos ⁡ B + cos ⁡ A sin ⁡ B. So by applying the above formula we get, sin 105 ∘ = sin (60 ∘ + 45 ∘) = sin 60 ∘ cos 45 ∘ + cos 60 ∘ sin ...sin(285) sin ( 285) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.
