/* Nonlinear Dependent Sources */
The second example is a voltage-controlled current source. v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.
The following mathematical functions defined for real [[variables]] can be used in the expressions:
abs, acos, acosh, asin, asinh, atan, atanh, cos, cosh, exp, ln, log, sin, sinh, sqrt, tan.
