(sqrt((a^2/4x)+ b)-((1/2)(a/sqrt(x))

I am defining my variables as a and b, (Parameter Names) but it does not put out values for y when I do a simulation.

My first suggestion to you would be to check your syntax. After a quick glance at the equation I can see at least two different errors. The first mistake in the equation is that you have used 7 opening parentheses and only 5 closing parentheses. For the equation to work, there must be an equal number of each. The second error is that the term 4x lacks an operator. A multiplication symbol is required between the 4 and the x in order for this to make sense to Origin. Once you have addressed these issues, try simulating the equation again.

If you find that you are unsuccessful after making these corrections, please contact us here at Microcal Technical Support. Be sure to provide your serial number and a step-by-step explanation of what you are doing to simulate the equation. Once we confirm that you are a registered user, we will be happy to assist you further.
