If cosh theta = 3, then the value of cosh 3 theta =

A : If tanh 5 sinh theta = cosh 10 - then theta = 10 R : cosh 2 theta - 1 = "2 cosh"^2 theta

The curve represented by x=a(cosh theta+sinh theta), y=b(cosh theta-sinh theta) is

If ("3 sinh "2 theta)/("5 + 4 cosh "2 theta) = 1 , then tanh ""^2 theta + 6 tanh theta is equal to

Observe the following statements: Assertion (A) : 2 cosh 3 cosh5 = cosh8 + cosh2 Reason (R ) : 2cosh alpha cosh beta = cosh (alpha+beta)- cosh(alpha-beta) Then the true statement among the following is
