$$\sum_{n=1}^{6} \sin^{2}{\left(x^{n} \right)}$$
Sum(sin(x^n)^2, (n, 1, 6))

$$\sin^{2}{\left(x \right)} + \sin^{2}{\left(x^{2} \right)} + \sin^{2}{\left(x^{3} \right)} + \sin^{2}{\left(x^{4} \right)} + \sin^{2}{\left(x^{5} \right)} + \sin^{2}{\left(x^{6} \right)}$$
sin(x)^2 + sin(x^2)^2 + sin(x^3)^2 + sin(x^4)^2 + sin(x^5)^2 + sin(x^6)^2
