Fortran File not written after subroutine call
I'm testing a part of a code and I have a problem. After the subroutine call at line 44 (CALL ZEIGSUB), nothing is written in UNIT NRES. The other units are written correctly. Here's the code: PROGRAM TEST IMPLICIT NONE complex *16, allocatable :: KSTAR(:,:), VR(:,:), CM2(:,:) real *8...- dilasluis

Undergrad Solving for x in an equation involving trigonometric functions
I'm just writing equations for the sake of it... I'm not trying to solve them... And would this make sense: If I would make an average of the equation and solve for x, like this: Suppose you have: x\cos\theta - x^2 \sin^2\theta - \csc\theta\cot\theta = 0 then to find a solution to x... -

Undergrad Solving for x in an equation involving trigonometric functions
I don't know if you will understand... but I want to know if any value for the angle, as long as it has a finite result, can be used to solve an equation with unknown angles. How would you solve this, for instance: x \sin \theta + \sqrt{x \cos \theta} = 0 ? Could you assume any value... -

Undergrad Solving for x in an equation involving trigonometric functions
That sine actually made me think on something, even if it holds, the equation would not be valid for that particular value of \theta . -

Undergrad Solving for x in an equation involving trigonometric functions
Sorry, bad choice on the sine... But imagine that you have the following equation: x \cos \theta - y(\theta) \cos^2\theta = 0 I wish to find a solution for x. What I want to know is if it is equivalent: x = y (0 \deg) = \frac{y (45 \deg) \frac{1}{2}}{\frac{1}{\sqrt{2}}} = \frac{ y... -

Undergrad Solving for x in an equation involving trigonometric functions
Angle panic! When we have a relation like, for instance, f(\theta) + g(\theta) = constant where \theta is an angle, does it hold for any angle such that we can do f(0 \deg) + g (0 \deg) = 0 and we would obtain an universal result? I mean, imagine f(\theta, x) = x \sin \theta , then... -

Substitution Rule for Integrals: Solving for the Unknown Variable
My biggest problem with this question is f(z) in both sides of the equation... and how do I change the integral from left side to the right.- dilasluis

Substitution Rule for Integrals: Solving for the Unknown Variable
z is a function of t, but not explicit, actually V_z = \frac{dz}{dt} was the relation from which we took d t = \frac{dz}{V_z} . V_z = cte- dilasluis

Substitution Rule for Integrals: Solving for the Unknown Variable
Hello! My problem is the following: Is \int_a^b f(z) dt = \int_{g(a)}^{g(b)} f(z) \frac{1}{g} dz ? \frac{dz}{dt} = g Thank you!- dilasluis

How can the volume of water needed to melt an iceberg be determined?
I solved the problem considering that the equilibrium temperature is 0ºC. The iceberg is melted and it lowers the water temperature around it to 0ºC. Anyone has any idea?- dilasluis

Nd2Fe14B: Molecular Structure Explained
Thank you and by the way... That wasn't the only picture I've found... I've got other that is more explicit than the one I've pasted the link (that was just for people who didn't need to know how it looked like as much as i did)... but I'm still trying to figure out what is the diference...
