Sin 75 Degree. If playback doesn't begin shortly, try restarting your device. What is the exact value of sin (75) degrees.
Is there exact values for sin (15 degrees) and cos (15 from www.quora.com
Exact value of sin 75 + sin 15. Sin(a+b) ≡ sin(a)cos(b) + sin(b)cos(a) ⇒ sin(75°) = sin(30+45)° = sin(30°)cos(45°) + sin(45°)cos(30°) Sin 75° sin 75° = sin (45° + 30°) = sin 45° cos 30° + cos 45° sin 30° = 1/√2 × √3/2 + 1/√2 × 1/2 = 1/√2 (√3/2 + 1/2) = (√𝟑 + 𝟏)/ (𝟐√𝟐) sin (x + y) = sin x cos y + cos x sin y putting x = 45° and y = 30°.

Sin(a+b) ≡ sin(a)cos(b) + sin(b)cos(a) ⇒ sin(75°) = sin(30+45)° = sin(30°)cos(45°) + sin(45°)cos(30°) Sin(30+45) sin ( 30 + 45) apply the sum of angles identity. In order to calculate it, we have to simplify the right hand expression of the equation.
Sin(30)Cos(45)+Cos(30)Sin(45) Sin ( 30) Cos ( 45) + Cos ( 30) Sin ( 45) The Exact Value Of Sin(30) Sin ( 30) Is 1 2 1 2.
#sin(a+b) = sinacosb+cosasinb# ∴ #sin(75) = sin(45)cos(30) + cos(45)sin(30)# we can use the unit circle to work out the values. #sin(75) = sqrt2/2·sqrt3/2 + sqrt2/2·1/2 = sqrt2/4(sqrt3+1)# #sin(75) = (1+sqrt3)/(2sqrt2)# The sine of angle 75 degrees is expressed as a mathematical expression in numerical form.
