2016-11-24 15:43:34 -0600 | commented question | Solving large trigonometric fucntions @tmonteil I was expecting a set of 4 solutions over the interval of 0 to 2*pi for phi. I solved this problem earlier on Wolframalpha before I added the terms sigma_a1 and sigma_a2 to my equations and got the following for one solution (note that variable names are different but the problem was essentially the same) t = -cos^(-1)((-sqrt((2 F X Y^2 Z cos(2 a) - 2 F X Y^2 Z)^2 - 4 (-4 F^2 X Y cos(a) + 2 F^2 X^2 + 2 F^2 Y^2) (4 F^2 X Y cos(a) - F^2 Y^2 cos(2 a) - X^2 Y^2 Z^2 cos(2 a) - 2 F^2 X^2 - F^2 Y^2 + X^2 Y^2 Z^2)) - 2 F X Y^2 Z cos(2 a) + 2 F X Y^2 Z)/(2 (-4 ...

2016-11-23 19:03:19 -0600 | asked a question | Solving large trigonometric fucntions Hi everyone, I'm new to sage and would like to use it to give me an exact solution to the derivative of a large trig function. I have been tinkering around with the different trig simplification routines to no avail. Here is the current incarnation of my code: Sorry, I do not know how to make the code appear in a window. The final result it gives me is: [sin(phi + theta) == M_1*sin(phi)/M_2] Can someone please help me or at least point me in the right direction. Thanks. |
