Enabling habitation in warmer environments.

Work would be greatly reduced, if not completely shutdown when summer heat overwhelmed equipment and personnel.

Even paperwork: think of writing a letter or doing payroll with sweat dripping on the curled up humid papers!!

A/C is considered one of the most important of innovations in the 20th century.

Cooler, dehumidified factories and workspaces increased productivity exponentially.

Sergio039 [100]

<h2> $\sin \theta=\dfrac{p}{h} =\dfrac{-7}{\sqrt{85} }$ , $\cos \theta=\dfrac{b}{h} =\dfrac{6}{\sqrt{85}}$ , $\tan \theta=\dfrac{p}{b} =\dfrac{-7}{6}$ ,</h2><h2> $\sec \theta=\dfrac{h}{b} =\dfrac{\sqrt{85} }{6}$ and $\csc \theta=\dfrac{h}{p} =\dfrac{-\sqrt{85}}{ 7}$ </h2>

Explanation:

Given,

$\cot \theta= \dfrac{-6}{7}$

To find, the exact values of the five remaining trigonometric functions of $\theta$ = ?

We know that,

$\cot \theta= \dfrac{-6}{7}=\dfrac{b}{p}$

Where, b = base and p = perpendicular

By Pythagoras's theorem,

Hypotaneous, $h=\sqrt{p^2+b^2}$

$=\sqrt{(-6)^2+7^2}=\sqrt{36+49} =\sqrt{85}$

In IVth quadrant,

$\cot \theta$ and $\sec \theta$ are positive.

$\sin \theta=\dfrac{p}{h} =\dfrac{-7}{\sqrt{85} }$ , $\cos \theta=\dfrac{b}{h} =\dfrac{6}{\sqrt{85}}$ , $\tan \theta=\dfrac{p}{b} =\dfrac{-7}{6}$ ,

$\sec \theta=\dfrac{h}{b} =\dfrac{\sqrt{85} }{6}$ and $\csc \theta=\dfrac{h}{p} =\dfrac{-\sqrt{85}}{ 7}$

Why is this relationship shown as a cycle

Aleks [24]

For rock cycle, it’s just part of the system of rocks being created and destroyed in cycles. Since it’s a model that describes formation breakdown and reformation of rocks. And of course the result is either sedimentary, metamorphic, or igneous.
