Question 888695: 1.write the first trigonometric function in terms of the second for theta in the given quadrant cot theta sin theta in quadrant 2
2.find an angle between 0 and 2pi that is coterminal with the given angle. 19pi/4
3. Find the period for the graph function y= 1/2sec(x-pi/4)

1.write the first trigonometric function in terms of the second for theta in the given quadrant cot theta sin theta in quadrant 2
cot(t) in QII is negative
sin(t) in QII is positive
-----
Ans:: cot(t) = -sqrt(1-sin^2(t))/sin(t)
-----------------------------------------------
2.find an angle between 0 and 2pi that is coterminal
with the given angle. 19pi/4
19pi/4 = 4pi + (3/4)pi
Ans:: (3/4)pi
===========================
3. Find the period for the graph function y= 1/2sec(x-pi/4)
Period = 2pi
====================
