Solve Block help

Question

Hej Guys, i am new to Mathcad and not very familar with it i have a worksheet with some functions and no i wanted to use the solveblock to find some solutions for me but i have no idea how i should write it down.

i added the worksheet with the functions. i have a function with two Variables that where i want to find those two variables when i only know one result of the two out put results that the funcions brings me.

the constraints i have and the expted result i put to the worksheet. maybe someone can give me some advise on how the solveblock need to be set up for a function with two variables?

Kind Regards

Markus

See if the attached file (Prime 9 format) helps in any way.

You seem to have wrong or too few constraints to get the two values HPH and AA.

Furthermore it looks to me that you made a mistake in the usage of the angle AA.

You sure are better off if you use correct angle units throughout!

To display an angle x in degree simply evaluate x/deg=

To define a value as an angle in degree, apply the unit deg or °

In case you are still using Prime 7 and can't read the attached sheet, here the changes and additions I made as pictures:

Function calc_kinematics.backward_Z

I defined three new functions (not mandatory, see remark) which are then used in the solve block

The solve block returns different results for different guess values, but all results returned are valid as they fulfill the given two constraints.
