Verify sin^4x − sin^2x = cos^4x − cos^2x is an identity

Inga [223]

Answer:

<h2>It's an identity</h2>

Step-by-step explanation:

$\sin^4x-\sin^2x=\cos^4x-\cos^2x\\\\L_s=\sin^4x-\sin^2x=\sin^2x(\sin^2x-1)=\sin^2x(-\cos^2x)=-\sin^2x\cos^2x\\\\R_s=\cos^4x-\cos^2x=\cos^2x(\cos^2x-1)=\cos^2x(-\sin^2x)=-\sin^2x\cos^2x\\\\L_s=R_s\qquad\bold{CORRECT}$

$\text{Used:}\\\\\sin^2x+\cos^2x=1\Rightarrow\left\{\begin{array}{ccc}\cos^2x=1-\sin^2x\\\sin^2x=1-\cos^2x\end{array}\right\Rightarrow\left\{\begin{array}{ccc}-\cos^2x=\sin^2x-1\\-\sin^2x=\cos^2x-1\end{array}\right$

Write an equation in point slope from for the line through the given point which the given slope

shusha [124]

The equation in point slope is $y-3=6(x-8)$ which is mentioned in option C If the line through the given point which the given slope (8,3), m=6.

Step-by-step explanation:

The given is,

The point - ( 8,3 )

Slope, m = 6

Step:1

Formula for slope of line is,

$Slope,m=\frac{y_{2}-y_{1} } {x_{2}- x_{1} }$ ..................(1)

Here, $(x_{1} ,y_{1} )$ and $(x_{2} ,y_{2} )$ are points and slope (m)

Step:2

From given,

$(x_{1} ,y_{1} )$ - (8, 3)

$(x_{2} ,y_{2} )$ - (x, y)

Substitute the values of points and slope in the equation (1),

$6=\frac{y-8 } {x- 3 }$

Take ( ${x- 8 }$ ) in left side,

$6(x-3)=(y-3)$

$(y-3)=6(x-3)$

Result:

The equation in point slope is $y-3=6(x-8)$ which is mentioned in option C If the line through the given point which the given slope (8,3), m=6.
