Hi, can someone help me with the above question? Thanks! Otto

Hello Mark, I have done the code, and its working, but I am getting the following error: "warning:comparing floating point quantities for equality may give misleading" would you please like to help me fixing what I am doing wrong? The Code: am multitask_trig ! This program solves three...

Well, I think I have solved the program: I am testing it with an online chart and it seems that is now properly working, Thanks!

Very nice! Will try that...

Got it, thanks!

That's exactly what I am doing, in fact I have about 6 or 7 sucessful programs made in Fortran 95, here a copy of one of them: ! New Quadratic formula calculator program new_quad_solve implicit none real :: a, b, c real :: disc, root1, root2 print *, ' Enter values for a, b...

Thank you Mark! I have followed all your comments, yes my bad being so novice on this sorry for that! I was following another's solution on the net, but yes it does make a sense not valuating the formula if equals to 1, I felt that could no affect the final solution, since no trying to give 1...

Whatever I do the result is the same:

Well, I have another problem here, no matter what number I do assign to X the result is the same, something is wrong, here the complete code: program complex_value implicit none ! This program solves the complex value of inverse SIN when it is higher than 1 real :: x real :: arcsin...

I have a fantastic HP 41CV and the equivalent in my iPhone, and have also three more apps: Mathway, Calculator Plus, and GeoGebra graphing app, will give some of them a try to solve this, not that do not trust to Fortran... is why you know I am totally newbie in this language

Thanks it seems that is now running, now do you know how can I test if the results are ok? It seems that there's no calculator that actually could do imaginary or complex calculations.

Ok what would be the order? I am trying here and there with no success at all.

Thanks Berkeman, I am actually interested in Java, I have some other books waiting for that, my older brother said that Java runs some applets with 2D input that could get some nice results, but at this time I wanted to solve first my issues in Fortran, don't get me wrong, but as I have solved...

Hi, I've never said Fortran was the problem, I am an industrial designer fully pasionated with math, recently I came across with an old book of Fortran90/95 and gave it a try, and I have felt in love with the results, at this time I could "write" about 6 programs including the quadform solution...

Hi, I am trying to run this program and I am having a warning: "warning 298 - value X has been used without being given an initial value" Here is my code: [moderator: code tags added] real :: x real :: arcsin complex :: I = ( 0.0 , 1.0 ) print *, ' Enter the value of x ' if ( abs ( x ) >= 1...
