Answer 2

Answer:

cosh (2x) = 11/2

sin h (2x) = 5.4

Step-by-step explanation:

sin h ( 2x) = 3/2

use identity

cos h (2x) = cos h ² x + sin h ² x

sin h (2x) = 2 sinhx coshx

cosh²(x) -sin h²(x) =1

now

cosh² (x) =1+sin h²(x)

               = 1+ (3/2)²

               = 13/4

cosh (x)= $\frac{\sqrt{13} }{2}$

cos (2x) =  cos h ² x + sin h ² x

             = 13/4 + 9/4

             = 22/4

              = 11/2

sin h (2x)  = 2 sinhx coshx

                = 2 x 3/2 x $\frac{\sqrt{13} }{2}$

                = 5.40

hence

cosh (2x) = 11/2

sin h (2x) = 5.4
