## Examples of valid and invalid expressions

 Function to integrate Correct syntax is Incorrect syntax is $$(2x+1)^6$$ (2x+1)^6 [2x+1]^6 $$\frac{10x + 1}{x^2-4}$$ (10x+1)/(x^2-4) 10x+1/x^2-4 $$\left(ln(x)\right)^2$$ ln(x)^2 ln^2(x) $$x ~ ln\left(\frac{x-1}{x+1}\right)$$ x*ln((x-1)/(x+1)) x*ln(x-1)/(x+1)
