How do you solve cot^2x + cscx= 1 <br>(0,2pi)

Nastasia [14]

$\bf 1+cot^2(\theta)=csc^2(\theta)\implies cot^2(\theta)=csc^2(\theta)-1
\\\\\\
csc(\theta)=\cfrac{1}{sin(\theta)}
\\\\
-------------------------------\\\\
cot^2(x)+csc(x)=1\implies csc^2(x)-1+csc(x)=1
\\\\\\
csc^2(x)+csc(x)-2=0\implies [csc(x)-2][csc(x)+1]=0\\\\
-------------------------------\\\\$

$\bf csc(x)-2=0\implies csc(x)=2\implies \cfrac{1}{sin(x)}=2\implies \cfrac{1}{2}=sin(x)
\\\\\\
sin^{-1}\left( \frac{1}{2} \right)=\measuredangle x\implies \frac{\pi }{6}~~,~~\frac{5\pi }{6}=\measuredangle x\\\\
-------------------------------\\\\
csc(x)+1=0\implies csc(x)=-1\implies \cfrac{1}{sin(x)}=-1
\\\\\\
\cfrac{1}{-1}=sin(x)
\implies 
-1=sin(x)\implies sin^{-1}(-1)=\measuredangle x\implies \frac{3\pi }{2}=\measuredangle x$

If f(x) = 1/6 x-8, then f^-1(x)=

bezimeni [28]

Answer:

f^-1(x) is 6x + 48

f(x) = 1/6x - 8

To find f^-1(x) equate f(x) to y

That's

f(x) = y

y = 1/6x - 8

Next interchange the terms

We have

x = 1/6y - 8

Make y the subject

Multiply through by 6

We have

6x = y - 48

y = 6x + 48

Therefore f^-1(x) is 6x + 48

Hope this helps you
