Упростим каждый член. Given trigonometric ratio: sin 75 ∘. sin 75° = cos (15° + 75° ) = cos 90° = 0 [since cos (A + B) = cos A. #sin(A-B)=sinAcosB-cosAsinB# so #sin15^@=sin(75^@-60^@)=sin75^@cos60^@-cos75^@sin60^@# BUT we don't know sine and cosine of #75^@#. Sin 75⁰ cos 15⁰ Rumus yang kita gunakan yaitu : 2 sinA cos B = sin(A+B) + sin(A-B) Sehingga, Sin 75⁰ cos 15⁰ = ½ (sin(75+15) + sin(75-15) = ½ (sin 90 + sin 60) = ½ (1 + ½*akar(3)) = ½ + ¼*akar(3) Jadi, sin 75° cos 15° = ½ + ¼*akar(3) b.9659, 0. So, sin 15° cos 15° = (1/2) sin (2*15°) = (1/2)sin 30° Q. Math notebooks have been around for hundreds of years.
