Find the numerical value of each expression. (Round your answers to five decimal places.)
(a) cosh 9
(b) cosh(ln 9)
I left my calculator at school but i will try searching on wolframalpha
Steve i got 4051.54203 for cosh 9 and for cosh(ln 9) i got 4.55556
To find the numerical value of each expression, we will use a scientific calculator or a math software that can calculate hyperbolic functions. In this case, we will use the cosh function.
(a) cosh 9:
To find the value of cosh 9, follow these steps:
1. Open a scientific calculator or math software.
2. Input "9" into the cosh function (usually denoted as "cosh()").
3. Press the equals (=) button or hit enter.
4. The calculator/software will provide the value of cosh 9.
The numerical value of cosh 9 is approximately 4051.54203 (rounded to five decimal places).
(b) cosh(ln 9):
To find the value of cosh(ln 9), follow these steps:
1. Open a scientific calculator or math software.
2. Find the natural logarithm (ln) of 9.
- Input "9" into the logarithm function (usually denoted as "ln()").
- Press the equals (=) button or hit enter.
- The calculator/software will provide the value of ln 9.
3. Input the resulting value of ln 9 into the cosh function.
4. Press the equals (=) button or hit enter.
5. The calculator/software will provide the value of cosh(ln 9).
The numerical value of cosh(ln 9) is approximately 4.81571 (rounded to five decimal places).
good. just enter your expression, and it will evaluate it. Bookmark that site!
sounds about right.
what, you don't have a calculator? Or an online one, such as wolframalpha.com?
I mean, geez...
