you are told that
tan s = + 6.86874..
so by the CAST rule, the angle must be in the I or III quadrant.
but our domain is from 0 to pi/2 which is only quadrants I and II.
and since they are using radians to describe the domain, we should also answer in radians.
set your calculator to radians,
inv tan or 2nd function tan
I got s = 1.42622 radians
ya see this somehow doesnt work on my calculator
so you have to enter inv tan 1??
let's try it with degrees first
set you calc to degrees
you should get 1
now work it backwards (the inverse)
at the top left you should have either an "INV" key or 2ndF key
you should get 45 degrees
If that doesn't work it could be that on your calc you have to enter the number first.
let me know if it worked.
If it worked, set your machine to radians and repeat the steps in the same way as noted above.
when i do tan 45 i get 1.6197..
do you know any site where i can use a calculator...
y912f, you have your calculator set to radians
yes, tan 45 radians = 1.6197
look for a key that says DRG, it will toggle your setting beteen degrees, radians and gradians
ya Damon already helped me understand the problem
i set it to radians. entered 1, atan and it equaled .785
then entered +, pi= 3.926radians
in other words 5pi/4
thanks for all your help tooo!!!!
