```python
(x**3 + y)**2
```




$\displaystyle \left(x^{3} + y\right)^{2}$




```python
solve(x**4 - 1,x)
```




$\displaystyle \left[ -1, \  1, \  - i, \  i\right]$




```python
f(x)
```




$\displaystyle f{\left(x \right)}$




```python
# 微分方程式
f(x).diff(x,x) + f(x)
```




$\displaystyle f{\left(x \right)} + \frac{d^{2}}{d x^{2}} f{\left(x \right)}$




```python
dsolve(f(x).diff(x,x) + f(x),f(x))
```




$\displaystyle f{\left(x \right)} = C_{1} \sin{\left(x \right)} + C_{2} \cos{\left(x \right)}$
