Hi all,

 

thank you for your help here:

a/ cos(w) + tan(w)*b = 3,5*c

a, b, c are known; angle w is unknown.

 

I want to solve the solution to w=...

 

But I can't do it. Whatever I try.

What's your solution proposal?

 

Thank you & kind regards,

Robert

1.  Draw a graph of the left-hand side against w and the right-had side against w to see where they intersect (perhaps multiply both sides by cos(w) first so that you don't get any divide by zeros).

 

2. Use a numerical technique like Newton-Raphson (though it's still a good idea to draw a graph first).

Hi Alan,

 

wow. That is the solution!

I followed your point 1 and finally found my answer :)

 

I'm so happy...

Thank you, from the depth of my heart!

 

Your karma has just risen by 1000 points minimum.

 

Keep up the good work here, you're

helping real people solve real technical problems.

 

Kind regards,

Robert
