Help on plotting sine wave and logarithm base e

Greeting,

I wanted to plot a function which is the addition of a sine wave and logarithm base e but I couldn't get it to work. Can somebody help me? I am new to Mathcad, please bear with me.Capture.PNG

You raise e to the power t, and t has a dimension (s). Any power that you raise e to MUST be dimensionless. You probably forgot to define and use the time constant (tau?) that t must be divided by in the exponent of e.

ttokoro (above) used a simple 1s for that.

And finally you defined V as an amplitude, but you don't use it, but that shouldn't present a plotting problem.

Anyway:

Success!
