If cot θ = 3/4 and the terminal point determined by θ is in quadrant 3, then:

OpenStudy (kj4uts):

OpenStudy (campbell_st):

well you should know cot = 1/tan so if cot = 3/4 then tan = 4/3 draw a diagram using the information |dw:1414995391664:dw| then you can find sin

OpenStudy (campbell_st):

opps forgot |dw:1414995556137:dw|

OpenStudy (kj4uts):

ok so d. tan 4/3 would be one of them

OpenStudy (campbell_st):

I think there are 2 solutions to the problem

OpenStudy (campbell_st):

and you are correct about tan

OpenStudy (kj4uts):

Yes there is more than one solution. Pythagoras theorem is a^2 = b^2 + c^2 right?

OpenStudy (campbell_st):

yes, you need to find the hypotenuse so you can look at sin, cos and csc

OpenStudy (kj4uts):

I think that tan θ = 4/3. sin θ = -4/5. cos θ = -3/5, csc θ = -5/4, sec θ = -5/3 Would that make the answers B. and D.
