Find the values of the trigonometric functions of t if sec t= 6/4, and the terminal point of t is in quadrent IV.
I am given a chart with blanks for sin t, cos t, tan t, and cot t. It asks for non decimal answers, so how would i do this, i am highly confused!

draw a triangle, with the hypotenuse extending out to the 4th quadrant. Drop another line to make a right angle with the x-axis. since cos is adjacent/hypotenuse, sec is 1/cos which would be
hypotenuse/adjacent. Label the triangle accordingly, The hypotenuse is 6, and the adjacent side 4.
Use the Pythagorean theorem to solve for the other side. Comes out to be sqrt(20). Keep in mind since you're in the fourth quadrant, and this is a y-value, it is actually negative.
Now you have all sides of the triangle, and following good ol' Soh Cah Toa, you can determine everything you need on that chart.
Good Luck, remember to draw pictures whenever in doubt.
