Thanks a lot for your useful comments. I think now I will be able to do.

Sorry picture was not attached. Here is the picture

Hi Thanks. Please have a look at the attached picture. The blue curve is position time and magenta is distance time. I just want to formulate a quick method to convert magenta curve to blue curve. Any possiblity please...

Thanks for your reply. Here are the details: Consider an ideal, one dimensional simple pendulum oscillating with respect to time. The graph attached is the distance-time graph of such pendulum's bob. The distance travelled keeps on increasing with respect to time. I want to sketch position or...

Dear friends, I have a distance (scalar) versus time graph of a flapping ornithopter. I want to sketch displacement (vector)versus time graph from this. I know that this should be like a sine wave. I dont know how to convert this. Actually distance time graph has accumulated displacement that I...

Hi every one. I have modeled a solid ellipse in fluid domain in a CFD analysis. I have measured induced horizontal force due to prescribed vertical flapping. I want to know will the ellipse start moving horizontally or not. any idea? or in simple words, what is the minimum force required to...

Thanks for the reply. In fact I did that too. I got a frequency spectrum plotted between fourier coefficients and frequency it reads as attached. Does that explain any symmetry in a meaningful way? In particular in the data obtained the blue curve is more regular and symmetric with respect to...

Hi Everyone. In one experiment I got output as in the attached picture. I want to compare the waves. Some waves look complete and symmetric and some seem to have irregularity/aperiodicity. Having got the numerical data (without defining equation), is there any way to measure the difference in...

Thanks for all the replies. I will see how I can apply fourier series. With regards Doctsh

I am looking for an equation for the wave given in the picture(sinewave with periodical missing waves). I know how sine wave, cos wave will look like, but looking for an analytical equation of this shape where peridocal removal of a wave: Please help me... Thanks Doctsh
