\bf cot(x)-\cfrac{csc^2(x)}{cot(x)}\\\\
-----------------------------\\\\
recall\qquad 
\begin{array}{llll}
\textit{Pythagorean Identities}
\\ \quad \\
sin^2(\theta)+cos^2(\theta)=1
\\ \quad \\
\boxed{1+cot^2(\theta)=csc^2(\theta)}
\\ \quad \\
1+tan^2(\theta)=sec^2(\theta)
\end{array}\\\\
-----------------------------\\\\
cot(x)-\left[ \cfrac{1+cot^2(x)}{cot(x)} \right]\impliedby \textit{distributing the denominator}
\\\\\\


\bf cot(x)-\left[ \cfrac{1}{cot(x)}+\cfrac{cot^2(x)}{cot(x)} \right]\implies cot(x)-\left[ tan(x)+cot(x) \right]
\\\\\\
cot(x)-tan(x)-cot(x)\implies -tan(x)

1) Para que valores reais de x o ponto P (3x -6, 2x +4) pertence ao 4º quadrante?
skelet666 [1.2K]

Answer:

There are no real values of x for point P to belong to the 4 quadrant

Step-by-step explanation:

<u><em>The question in English is</em></u>

To what real values ​​of x does the point P (3x -6, 2x +4) belong to the 4th quadrant?

we know that

A point in the fourth Quadrant has the x-coordinate positive and the y-coordinate negative

we have the point

P (3x-6, 2x+4)

3x-6 > 0 ----> inequality A  ( x-coordinate must be positive)

2x+4 < 0 ---> inequality B ( y-coordinate must be negative)

Solve Inequality A

3x-6 > 0

3x > 6

x > 2  -----> (2,∞)

Solve Inequality B

2x+4 < 0

2x < -4

x < -2 ----> (-∞,-2)

The solution of the system is

(-∞,-2) ∩ (2,∞)

therefore

The system has no solution

There are no real values of x for point P to belong to the 4 quadrant
