Find the values of the trig functions of t if sect=2 and sint<0.
Here are my answers, all work is shown below:
sect = 2
cost = 1/2
sint = -?(3)/2
csct= (2/?(3))
tant= ?(3)
cott= 1/?(3)
Solving for cost
sect= (1/cost) Therefore:
2 = 1/cost=1/2
Solving for sint
From the Pythagorean Identities we have:
sin^2t + cos^2t = 1
sin^2t + (1/2)^2 = 1
sin^2t = 1 - 1/4
sin^2t = 3/4
sint = ±?(3/4)
sint = -?(3)/2 (Negative because instructions say sint<0 ????
Solving for csct
csct=(1/sint)
csct= (2/?(3))
Solving for tant
tant=(sint/cost)
tant= [?(3)/2]/[1/2]
tant= ?(3)
Solving for cott
cott= 1/tant
cott=1/?(3)
Would someone tell me if I am correct?
