Hi guys, I eventually learnt how to use the symbolics now. I have written my equation, but when I want to solve it, it requires variable. Its not integral, just algebra, I dont know why it requires variable.

Please help guys.

For whatever variable you want to solve this equation?

And second.

Use please * between variables!

Hi Valery, thank you for your reply. But I dont quite understand. Its just algebra solving. The only variable I have is time. From most examples I see, they variable as a number. But I want it purely to be symbolic.

If this is the equation:

If I want to solve:

real(exp(1i*w(t)+*fi(t))+(cos(wRF(t))/sin(wRF(t)))

In this case, the variable is t. But I dont even need to mention t if I want to solve algebraically, right?

I just want to solve the interaction between exp, cos, and sin. Sorry if I am describing something wrong here, but I truly dont understand.

If I have to define a variable, how do i do it in the worksheet? I knoe defining a variable in terms of number in Mathcad is going to be t:=number. Right?

Please advice! Thank you very much.

Sorry w(t) etc is a function of t?
