Question

find degree and radian of function value of sec = sqrt(2)

Answer 1

help pls

Answer 2

rad = 6.412570906
deg=1.000304695

Answer 3

So you're looking for the angle whose secant is \[\sqrt{2}\]. \[\sec \theta\]\[ = 1/\cos (\theta)\], so the reciprocal is true, too.
\[\cos \theta=\frac{ 1 }{ \sec (\theta) }\]
\[\cos \theta =\frac{ 1 }{ \sqrt{2}}\]

Where on the unit circle is cosine \[\frac{ 1 }{ \sqrt{2} } or \frac{ \sqrt{2} }{2}\]?

\[\frac{ \pi }{ 4}\] radians or 45 degrees
