Question | Answer |
---|---|

d/dx (f*g)= | f'*g + f*g' |

d/dx (f/g)= | (f'*g - f*g')/g^2 |

d/dx [f(g)] = | f'(g) * g' |

d/dx (x^n) = | nx^-1 |

d/dx (sin x) = | cos x |

d/dx (cos x) = | -sin x |

d/dx (tan x) = | sec^2(x) |

d/dx (cot x) = | -csc^2(x) |

d/dx (sec x) = | sec(x) tan (x) |

d/dx (csc x) = | -csc(x) cot(x) |

d/dx (e^x) | e^x |

d/dx (a^x) | (ln(a))a^x |

d/dx (log(base a)^x) | 1/(ln a) * x |
