Using the Product to Sum Formula for Trig, Calculate Sin(45°)Sin(30°)

Sin(u)Sin(v) = | Cos(u - v) - Cos(u + v) |

2 |

In this case, u = 45 and v = 30

Sin(45)Sin(30) = | Cos(45 - 30) - Cos(45 + 30) |

2 |

Sin(45)Sin(30) = | Cos(15) - Cos(75) |

2 |

Sin(45)Sin(30) = | 0.49 - 0.3 |

2 |

Sin(45)Sin(30) = | 0.19 |

2 |

Sin(45)Sin(30) =
