Radian to degrees

$
0
0
I am new to using MathCad, but it seems that I should be able to figure out how to change from radians to degrees. The manual is pretty much worthless, and the help section merely states that MathCad gives results of trig functions in radian mode. No kidding. Any help is appreciated, and yes I feel like a moron.

MathCAD Prime 1.0 and PDESolve

HI Friends,

I have read in the Manual of MC Prime 1.0 that PDESolve is not working anymore.

Does anyone have any advices to this serious Problem? PDESolve is very important for math.

Thanks for answering.

using a vector inside an if statement

$

I am trying to create an expression where an if statement contains a vector. Mathcad gives an error stating that the value in the if statement must be a scalar. For example: H:= if(i< zmax/2, p1, p2) where i is a time vector. Is there a way to use a vector in an if statement?

Thanks,

Art

Mathcad 15 "onefn" function problems

$

I am having trouble with the onefn function in Mathcad 15.  I get double entries in the 1/f noise vector and if I take the CFFT(ofn) I get a zero as the first result.  Also I do not understand the mirrored magnitude plot of the 1/f Noise.  I also don’t understand why the range variable even starts at zero.  That would give infinity for 1/f.  See attached.

Solving Equations for undefined variable with units

$

So, I am confused on how to solve an equation for an unknown with units. I am not sure if I am having unit problems or if my way of stating variables is incorrect. I am simply just trying to solve for the variable "d" which should have units in length. How should I declare variables that rely on other known and unknown variables? When should I solve an equation symbolically and just numerically in terms of getting proper units? I am used to using maple 16 so switching to MathCAD has been fairly intiutive but I am failing to pick up on certain features. If you fix my MathCAD code, I should be able to figure it out from the fix solution. Thanks!

help exporting formula to text

$
0
0
Can anyone tell me how to convert a MathCAD formula to text? If I'm performing a symbolic manipulation on a complex expression, sometimes I will get the message "The Result is too long to display here: save to clipboard?" and the information in the clipboard is a text version of the formula. I cannot find a way to FORCE it to do this, short of performing arbitrary symbolic manipulations until the expression becomes too large to display.

What I'd like to do is take a lot of large formula that I've symbolically created in mathcad, and turn them into text so that I can paste them into a C program.

I've seen posts here to the effect that going from text to formula is hit or miss for different people, but I was hoping someone could tell me how to go the other way.

I'm using MathCAD 2001, by the way.
