Question

If cosh x = sec a then cosech x=​

Answer 1

Answer:

cot a

Step-by-step explanation:

sinhx=2ex−e−x

coshx=2ex+e−x

sinh2x=cosh2x−1

sinh2x=sec2α−1=tan2α

⇒sinhx=tanα

cosechx=sinhx1=cotα

Answer 2

Answer:

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x
