Use identities to find the exact values at alpha for the rem
Use identities to find the exact values at alpha for the remaining five trigonometric functions. sec alpha = - 7 Squareroot/3 and alpha is in quadrant III cos alpha = sin alpha = csc alpha = tan alpha = cot alpha =
Solution
given seca = - 7sqrt3/3
cosa = 1/seca = - 3/(7sqt3)
sina = - sqrt138/(7sqrt3)
csca = 1/sina = - 7sqrt3/sqrt138
tana = sina/cosa = sqrt138/3
cota = 1/taana = 3/sqrt138
