Question

PLZ I need help!!!!!

Answer 1

Answer:

The Answers are

$\csc (-45) =-\sqrt{2} \\\\\sec (-45) = \sqrt{2}\\\\\cot (-45) = -1$

Step-by-step explanation:

Let we Know some Identities

cosec (-θ) = - cosec (θ)

   sec (-θ) = sec (θ)

    cot (-θ) = - cot (θ)

Also,

$\csc (45) =\sqrt{2} \\\\\sec (45) = \sqrt{2}\\\\\cot (45) = 1$

Therefore,

$\csc (-45) =-\csc (45)=-\sqrt{2} \\\\\sec (-45) =\sec (45) =\sqrt{2}\\\\\cot (-45) =-\cot (45)= -1$
