*This function shows the Base theta value.

*The basic theta function is defined to be the function <math> \theta</math>:<math>\mathbb{C} \rarr \mathbb{C} </math> given by    

*The basic theta function is defined to be the function <math> \theta</math>:<math>\mathbb{C} \rarr \mathbb{C} </math> given by <math>\theta(z):= \theta(\tau)(z):=\sum_{n\in z} exp(\pi in^2 \tau)exp(2\pi inz)</math>

*The function <math>\theta</math> depends on <math>\tau</math>τ .  

*The function <math>\theta</math> depends on <math>\tau</math>τ .  

*So for each <math>\tau \in \mathbb{C}</math> with <math>Im \tau \ge  0</math> we get a (not necessarily different) basic theta function.
