Solved!

Solve numerical equation

HP Recommended
HP Prime

Hello,

 

I am trying to solve the following equation,

                            'sin(beta-0.361) + sin(0.361)*e^(-beta/0.377) = 0'

It should give me beta = 3.5 rad = 201 degrees. However, I tried to solve using 'Solv App > CAS > Solve > Numerical' and other ways and I couldn't get the correct result. Is there a different way to solve this?

Hello Pedro

 

I assume you might be also Brazilian, but anyway I'll reply in English.

 

Please take a look at chapter 22, starting in page 370, of User's manual. There you'll find detailed description of SOLVE function to be used in CAS mode.

 

Then look at the attached picture, showing the solution for your equation through SOLVE function.

 

Regards,

Ciro.

Hello Ciro,

 

First of all, thank you for your reply, and yes, I am Brazilian. 

 

Regarding your reply, I tried to use the method described by the section you pointed out in the User's Manual, but I still couldn't get it right. Coul you upload the picture again, please? I wasn't able to visualize it.

 

Thank you,

 

Pedro.

Hello again Ciro,

 

I reloaded the page and I could see the picture. After that, I tried to solve again and it worked.

 

Thank you,

 

Pedro.
