Answer:
The Answers are
[tex]\csc (-45) =-\sqrt{2} \\\\\sec (-45) = \sqrt{2}\\\\\cot (-45) = -1[/tex]
Step-by-step explanation:
Let we Know some Identities
cosec (-θ) = - cosec (θ)
sec (-θ) = sec (θ)
cot (-θ) = - cot (θ)
Also,
[tex]\csc (45) =\sqrt{2} \\\\\sec (45) = \sqrt{2}\\\\\cot (45) = 1[/tex]
Therefore,
[tex]\csc (-45) =-\csc (45)=-\sqrt{2} \\\\\sec (-45) =\sec (45) =\sqrt{2}\\\\\cot (-45) =-\cot (45)= -1[/tex]
