<PRE><B>Question 289100</B>
I must find the exact value of six trig functions of pi/4 radians.
sin pi/4 csc pi/4
cos pi/4 sec pi/4
tan pi/4 cot pi/4
please help me i have no idea how to do this. thank you i really appreciate any help.

1. have your calculating device set to radians
2. sin = 1/csc; cos = 1/sec; tan = sin/cos = 1/cot

sin pi/4 = sqrt(2)/2
cos pi/4 = sqrt(2)/2
tan pi/4 = 1

3. the other 3 are the reciprocals
