Question

cot(csc inverse sqrt 10) Find the exact value, express in radians
will fan and medal

anonymous · Answer

express in radians 
right !! how about "express is euros"  or "express is centigrade"

anonymous · Answer

|dw:1430963557780:dw|

anonymous · Answer

find $a$ via pythagoras then you can take any trig ration you like

anonymous · Answer

express in radians?  did someone actually write that?  it is not an angle you are looking for, it is just a number

anonymous · Answer

For the a I got sqrt 9

anonymous · Answer

you should find that the missing side is 3

anonymous · Answer

yeah $\sqrt 9=3$ right?

anonymous · Answer

Oh yeah

anonymous · Answer

so cotangent is $\frac{3}{1}=3$

anonymous · Answer

but it sure as hell isn't three radians, it is the number three

anonymous · Answer

tell your math teacher that "express in radians" business is just plain nonsense

hehe was slow lol

anonymous · Answer

Thats okay, thanks :)

anonymous · Answer

hmm 
$$\csc(\theta)=\sqrt{10}\iff \sin(\theta)=\frac{1}{\sqrt{10}}$$

anonymous · Answer

it is very unlikely that the sine of anything is the square root of ten

anonymous · Answer

@xapproachesinfinity you got your triangle labelled goofy 
root ten should be the hypotenuse

xapproachesinfinity · Answer

lol not thinking hehe

xapproachesinfinity · Answer

at some point i was thinking of sin inverse not csc inverse lol
