odesolve variable undefined

[RD_10274658]

Hi Guys

I am a civil engineering student and completly new to mathcad. I wanted to do the example 3-3 (solve differential equations with a solve block).

I did it exactly as shown in the task but I always get the error that the variable is not defined. I have no idea what I am doing wrong and would be grateful if somebady could help me.

Greetings

Hi,

Corrected file.

Needs CTRL= for the equalities in the solve block

Needs CTRL' for the differentials

Cheers
