Sin15 Degrees. ( 75 ∘) = 6 + 2 4. Sin 60° = √3 /√4 = √3 /2.

135 is an obtuse angle since it is greater than 90° sin(135) = √ 2 /2 in microsoft excel or google sheets, you write this function as =sin(radians(135)) Sin 75 we can write it as. Divide the angle 5 θ as sum of two angles and it is better to write the compound angle as the sum of 2 θ and 3 θ.
Sin 90° = √4 /√4 = 1.
= √ 2 − √3 4. The sine of angle five pi by twelve radian can be proved exactly in fraction form in trigonometric mathematics. Calculation of the value of sin 45 degree in fraction.
Sin (A + B) = Sin A.
( 90 ∘ − 3 θ) Divide the angle 5 θ as sum of two angles and it is better to write the compound angle as the sum of 2 θ and 3 θ. Cos b + cos a.

2 θ = 90 ∘ − 3 θ. The main trick is to use the relationship between the angle 15° and the standard angles 0°,30°,60° and 90°. Answered 8 months ago · author has 203 answers and 26.3k answer views.
Since We Know That 15 Is Half Of 30, We Can Plug 30∘ In As Θ And Simplify:
Sin(15∘) = sin(30∘ 2) = √ 1 − cos(30∘) 2. 2 θ + 3 θ = 90 ∘. 135 is an obtuse angle since it is greater than 90° sin(135) = √ 2 /2 in microsoft excel or google sheets, you write this function as =sin(radians(135))
