Mathematics

Answer:

Steps shown below

Step-by-step explanation:

We will simplify this using definitions and identities. Let's start.

\frac{cos(x)}{sin(x)tan(x)}

Using tanx=\frac{sinx}{cosx}, we have:

\frac{cos(x)}{sin(x)\frac{sin(x)}{cos(x)}}\\=\frac{cos^2(x)}{sin^2(x)}

Using cot(x)=\frac{cos(x)}{sin(x)}, we have:

\frac{cos^2(x)}{sin^2(x)}\\=cot^2(x)

Hence, proved.

Shannon did not mix the correct shade. Cause the correct ratio of blue and red is 7:5. While Shannon mix 12:8=3:2 which is not equal to 7:5.

A Pythagorean triple is a triple of natural numbers satisfying the equation a^2+b^2+c^2.
Softa [21]
X, x+2 - two consecutive odd or even numbers
Add the reciprocals of these numbers.
\frac{1}{x}+\frac{1}{x+2}=\frac{x+2}{x(x+2)}+\frac{x}{x(x+2)}=\frac{x+2+x}{x^2+2x}=\frac{2x+2}{x^2+2x}


Now add the squares of the numerator and denominator, as in the example.
(2x+2)^2+(x^2+2x)^2= \\ 4x^2+8x+4+x^4+4x^3+4x^2= \\ x^4+4x^3+8x^2+8x+4

So this number has to be a perfect square.
x^4+4x^3+8x^2+8x+4= \\
x^4+2x^3+2x^2+2x^3+4x^2+4x+2x^2+4x+4= \\
x^2(x^2+2x+2)+2x(x^2+2x+2)+2(x^2+2x+2)= \\
(x^2+2x+2)(x^2+2x+2)= \\
(x^2+2x+2)^2
It is a perfect square, so this method always works.

The numbers 2x+2, \ x^2+2x, \ (x^2+2x+2)^2 are a Pythagorean triple for any x \in \mathbb{N^+}.
