cosh^2 x - sinh^2 x = 1
cosh x = 1+ sinh^2 x
cosh x = 1+(-3/5)^2
cosh x = 1+9/25 = 34/25
cosh 2x = 2 sinh x cosh x
cosh 2x = 2 (-3/5) (34/25)
=-204/125
If x equals 35, then -x equals -35.

Find the measure of this angles m1 equals 123 m8 equals?
EC = 9 in. CD = in. Find ED.
If x equals 35, then -x equals -35.
To find the conjugate of ( \cos z ) for a complex number ( z = x + iy ) (where ( x ) and ( y ) are real numbers), you can use the formula for the cosine of a complex argument: [ \cos z = \cos(x + iy) = \cos x \cosh y - i \sin x \sinh y. ] The conjugate of ( \cos z ) is obtained by taking the complex conjugate of the expression, resulting in: [ \overline{\cos z} = \cos x \cosh y + i \sin x \sinh y. ]
