Question

FInd exact value of csc ^-1 (sqrt2)

Answer 1

I have to review this again, sorry.

Answer 2

@rascal get it?

Answer 3

@RaphaelFilgueiras mind if i rewrite it using equation editor?

Answer 4

go on

Answer 5

\[\alpha=arccsc(\sqrt{2})->\csc(\alpha)=\sqrt{2}->\frac{ 1 }{ \sin(\alpha) }=\sqrt{2}->\sin(\alpha)=\frac{ \sqrt{2}}{ {2} }\]

Answer 6

How did you go from 1/sin(alpha)=sqrt(2) to sin(alpha)=sqrt(2)/2? I understand how you got 1/sin(alpha)=sqrt(2).

Answer 7

\[->\alpha= \pi/4\]
