Good day,hope I'm welcome
I'm having problem solving these
Find the circular functions of the following:
a. 36 deg
b. 22 deg and 30 minutes
c. 15 deg = ( 30 deg / 2 )
For a. I tried to find special angles(30,60,45,and other quadrantal angles) that would sum up to 36 deg , but I just can't find any.
Same goes for letter b.
And for letter c. I can't think of any procedure that will direct me to the correct answer, using 30 deg / 2.
Hoping for replies.
We are asked to find the
sine, cosine, tangent, cosecant, secant, cotangent of the following angles
like sin30 deg = 1/2.......etc
It would be best if it is in radical form
Hope it clears things.
Thanks for any help
Thanks I got the sin, cos, and the tan, already
So..........How do I get the sec, csc, cot ?
Should I get their reciprocals?
and when should I use these formulas?
tan y/2 = 1- cos y / sin y
tan y/2 = sin y / 1 + cos y
Yes, once you've got sin, cos and tan, just take their reciprocals and you have the csc, sec and cot.

Never mind my other question. I had an error there
My question was supposed to be
"when should I use these identities
tan^2 y /2 = 1 - cos y / 1 + cos y
tan y /2 = 1 - cos y / sin y
tan y /2 = sin y / 1 + cos y
since they are all Tangent-Half-Measure Identities" I was thinking they are all of different uses
Later on I found out they are all just equal, After some computations
As for letter a. how should I solve it?
Anyway thanks for the help!(Hi)
And HAPPY NEW YEAR TO ALL(Clapping), its December 31, 2008 here waiting for the New Year to come 1 hour or so from now its already 2009!!
