Prove the identity. cosh(−x) = cosh(x) (this shows that cosh is an even function.)

The identity is proved in the step-by-step explanation.

Step-by-step explanation:

The cosine hyperbolic function can be approximated by the following exponential equation:

For , we have that:

Since , the hyperbolic cosine is an even function.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
