cosh((zz)/2)=0

cosh (\frac{zz}{2}) = 0

No Solution for z \in R

Solution steps

cosh (\frac{zz}{2}) = 0

Rewrite using trig identities

\frac{e ^{\frac{zz}{2}} + e ^{- \frac{zz}{2}}}{2} = 0

\frac{e ^{\frac{zz}{2}} + e ^{- \frac{zz}{2}}}{2} = 0 : z = Undefined, z = - Undefined

z = Undefined, z = - Undefined

Since the equation is undefined for:

Undefined, - Undefined

No Solution for z \in R

t, 2 cos (t) = x

cos^{4} (x) = 1 - sin^{4} (x)

2 sinh (x) - 2 cosh (x) - 2 = 0

sec^{2} (x) + cot^{2} (x) = csc^{2} (x)

\frac{sin ( 7 9 ^{\circ} )}{12} = \frac{sin ( B )}{7}
