Answer by edwin mccravy (19308) ( show source ): Web find the exact value sin(75)+sin(15) simplify each term. It is the square root of two+ the square root of six then divided by 4. Sin (75) = sin (45 + 30) = sin (45)*cos (30) + cos (45)*sin (30) = [1/sqrt (2)]* [sqrt (3)/2] + [1/sqrt (2)]* [1/2] = 1/ [2*sqrt (2)]* [sqrt (3) + 1]. Web this video works to determine the exact value for the sine of 75 degrees in two different ways: Hence, the value of sin 75 is 3 + 1 2 2. Web sin(75) = sin(45 + 30) = sin(45)*cos(30) + cos(45)*sin(30) = [1/sqrt(2)]*[sqrt(3)/2] + [1/sqrt(2)]*[1/2] = 1/[2*sqrt(2)]*[sqrt(3) + 1] that is [sqrt(3) + 1] /. Web sin 75°= sin (45°+30°) =sin45cos 30+ cos45 sin30. Web what is the exact value of sin (75°)? Web what is the exact value of sin(75)?
Sin 75 ∘ sin 75 ∘ can be expressed as, sin 75 ∘ = sin ( 45 ∘ + 30 ∘). Web this video works to determine the exact value for the sine of 75 degrees in two different ways: Tan(30+45) tan ( 30 + 45) apply the sum of angles identity. Web find exact value of sin 75 degrees sin 75 degrees is the value of sine trigonometric function for an angle equal to 75 degrees. 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° +. Either of these three ways is. Answer by edwin mccravy (19308) ( show source ): The exact value of is. Split into two angles where the values of the six. 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 + solve now Sin 75 degrees can also be expressed using the equivalent of the given angle (75 degrees) in radians.
