1. For powers use ^. Example: x12= x^12 ; ex+2= e^(x+2)
2. For square root use "sqrt". Example: x+1−−−−−√= sqrt(x+1).
3. Supported constants: e, pi
4. Supported functions: sqrt, ln ( use 'ln' instead of 'log'), e (use 'e' instead of 'exp')
5. Please use '1/2(1-cos(2x))' instead of 'sin²x'.
6. Please use '1/2(1-sin(2x))' instead of 'cos²x'.
7. Please use '(1-cos(2x)/(1-sin(2x)' instead of 'tan²x'.
