tan t87 sin

tan t=-8/7 sin<0 Find cos t, sec t, csc t, sin t

Solution

tan t=opposite side/adjacent side =-8/7

opposite side²+adjacent side²=hypotenuse²

cost adjacent side/hypotenuse=7/[(-8)²+7²]

cost =7/[64+49]

cost =7/113

sect =1/cost =(113)/7

sint =opposite side/hypotenuse=-8/[(-8)²+7²]=-8/113

csct=1/sint=-(113)/8
