Use the double angle identity:


\sin^2\dfrac\pi{12}=\dfrac{1-\cos\frac\pi6}2


Then \cos\dfrac\pi6=\dfrac{\sqrt3}2, so you get


\sin^2\dfrac\pi{12}=\dfrac{2-\sqrt3}4

Consider the line y=9x-1.
OLEGan [10]

Step-by-step explanation:

Slope=9

i)

y−y1=m(x−x1)

When line is parallel

y+5=9(x-6)

y+5 = 9x - 54

<h3>59 = 9x-y </h3>

When line is perpendicular

y+5=-1/9(x-6)

9(y+5)= -1(x-6)

9y + 45 = -x+6

<h3>x+9y = -39</h3>
