Question

csc^2-4=0

Answer 1

csc^2=4

Answer 2

solve it now take sqrt both side

Answer 3

yes, and then take the inverse cosine of what you get.

Answer 4

\[\csc^2x-4=0\]

Answer 5

\[add~~4~~t o~~both~~sides,~~~~~~\csc^2x=4\]\[take~~a~~squ are~~r oot~~o f~~both~~sides,~~~~~~~cscx=2\]\[\csc ^{-1}(2),~~~~~~(or~~\sin ^{-1}(1/2))~~~~is?\]

Answer 6

30?

Answer 7

careful here

Answer 8

\[\csc^2(x)=4\\
\csc(x)=2,\csc(x)=-2\\
\sin(x)=\frac{1}{2},\sin(x)=-\frac{1}{2}\]

Answer 9

oh, yeah, forgot about the plus minus, ty, satelline...

Answer 10

it would be\[either~~~Sin ^{-1}(1/2)~~~or~~~~~~Sin ^{-1}(-1/2)\]

Answer 11

\[\cos^2x+2\cos x=3\]
