Hello!

When issuing into icas commandline, the output is
However, when issuing
the output is
Why is the output not consistent (either decimal result or same as input in both cases)? Can this be made consistent?

Hi!

Am I failing to find one or is it really missing?

I can find functions sinh, asinh, cosh, acosh, tanh, atanh, but cannot find coth and acoth.

Currently, I am workarounding this with coth definition from Wolfram Mathworld, but it would be nice to have these functions supported directly.

Thanks, you are very helpful.

Hi, I am having problem with calculation of definite integral: 1>> integrate(sin(2x)*e^(cos(x)^2),x,-(pi/4),pi/4) integrate(sin(2*x)*exp(cos(x)^2),x,-pi/4,pi/4) 2>> version() "giac 1.2.0-19, (c) B. Parisse and R. De Graeve, Institut Fourier, Universite de Grenoble I" Shouldn't the result be 0? Wolfr...

If I integrate expression that contains fraction power, I get weird result: 0>> normal(integrate((1) / (root(3, (x)^(2))), x)) Warning, integration of abs or sign assumes constant sign by intervals (correct if the argument is real): Check [abs(x)] 3*(x*sign(x))^(1/3)/sign(x) 1>> version() "giac 1.2....

Thank you for the answer.

Hi, using Giac version 1.2.0 I am facing wrong results for relatively simple integrals: 0>> integrate(x/(x^50),x) -1/805306368/(x^2/2)^24 1>> integrate(x/x^50,x) -1/805306368/(x^2/2)^24 2>> integrate(1/(x^49),x) -1/(48*x^48) 3>> version() "giac 1.2.0-19, (c) B. Parisse and R. De Graeve, Institut Fou...

Are there any Git, SVN or CVS repositories that contain the fix?

Thank you for explanation!

Hi! I have found a possible regression in solving certain system of inequalities. When using old version of icas command line tool: 0>> solve(list[(y)^(2) + 5 >= 2, 2 > y - 10, (y)^(2) >= 0], y) list[y<=0,((y>=0) and (y<=12))] 1>> version() "giac 0.9.9" 2>> When using the latest xcas for Mac OS: 0>>...

Hello! We are using Giac v1.2.0 compiled from source. We have found some inconsistencies in handling compound inequations. Namely: Input: solve((y)^(2) - 3.5 < 5 < y + 9, y) Output: Inequation inside inequation not implemented (y^2-7/2-y-9)<(5-y-9) Error: Bad Argument Value However, if we just sligh...
