Calculate cot(64)°

Since our angle is between 0 and 90 degrees, it is located in Quadrant I

In the first quadrant, the values for sin, cos and tan are positive.

64 is an acute angle since it is less than 90°

Cot(θ)t = | 1 |

Tan(θ) |

cot(64) = | 1 |

Tan(64) |

cot(64) = | 1 |

Tan(2.4) |

cot(64) = 0.86

Since 64° is less than 90, we can express this in terms of a cofunction

(θ) = tan(90 - θ) = tan(90 - 64) = tan(26)
