State restrictions for the given equation below
Genrish500 [490]

The restriction of the given equation is cos^{2}x =cos^{2} x,  other than 0≤x≤2π.

What is restriction of equation?

Restriction of the equation is the value of domain where the value is limited.

Given,

sin^{2} xcos^{2}x +cos^4x =(1-sinx)(1+sinx)

taking cos^2x common, we get

cos^2x(sin^2x+cos^2x)=1+sinx-sinx-sin^2x

we know

sin^2x+cos^2x=1\\cos^2x=1-sin^2x

we get,

cos^2x=cos^2x

and the restriction is 0≤x≤2π.

———Help pleaseeeee———
Maslowich

Answer:

Slope of line is \pi

Step-by-step explanation:

Given that the company logo has four concentric circles.

To plot the line on the graph take point as ( Diameter, Circumference )

Circumference of a circle is given by C=\pi D

Where D is the diameter.

To draw a line, we need at least two-point.

Now,

Take D=1

Circumference of a circle will be C=\pi D=\pi

Required point is (1,\pi)

Take D=0

Circumference of a circle will be C=\pi D=0 \pi

Required point is (0,0)

The slope of line is given by s=\frac{Y2-Y1}{X2-X1}

Hence,

s=\frac{Y2-Y1}{X2-X1}

s=\frac{0-[tex]\pi}{0-1}[/tex]

s=\frac{[tex]\pi}{1}[/tex]

s=\pi

Thus, Slope of line is \pi
