Hi guys,

Recently, I have tried to integrate function of the form:

f(x)= if x<100
g(x)
else
h(x)

over x=(0-105) using build in integral operator. However, there is an error: 'x-not defined'. I can easily overcome this problem by simply writing:

Int(f(x)) [from 0 to 100] + Int(g(x)) [from 100 to 105]

However, I think that a possibility of using user-created conditional functions in Integral or Derivative operators could be a very useful feature.

Best,
Daniel

Hello,

Do you use the Interactive SMath Handbook by Martin Kraska (Interactive books from Gallery) as the default Reference Book inside SMath?
Read the part about Integration from this book, please.
