标志
-p, --preview，预览而不是计算
-o, --output-type，选择输出类型，1表示漂亮；2表示乳胶，3表示正常
-u, --use-unicode，对符号使用unicode
^{answer>使用{cd5}换行
参数
-s, --use-scientific，用科学的符号记下近似答案，论证就是准确
-a --accuracy，评估的准确性
-c --copy，复制答案。1表示精确答案，2表示近似答案，3表示[确切答案，近似答案]列表
公式特定参数
-d --domain，给出要求解的域
-v --verify-domain，过滤掉不在域中的任何解决方案。不适用于solveset。必须设置此标志，以便域在使用“求解”而不是“解算集”求解时正常工作。方程组所需

Derive a function
Usage: caspy deriv EXPRESSION VARIABLE [ORDER] [AT_POINT] [FLAGS]
Example(s):
>>> caspy deriv x**x x
>>> caspy deriv sin(1/x) x 3 pi
微分方程
Solves a differential equation equation.
Separate equation by either a space or a =, but not both.
Usage: diff-eq LEFT_EXPRESSION RIGHT_EXPRESSION FUNCTION_TO_SOLVE_FOR [HINT] [FLAGS]
Example(s):
>>> caspy diff-eq f'(x) 1/f(x) f(x)
>>> caspy diff-eq f''(x)+3*f'(x)=x**2 f(x)
等式
Solves a normal equation.
Separate equation by either a space or a =, but not both.
Usage: eq LEFT_EXPRESSION RIGHT_EXPRESSION VARIABLE_TO_SOLVE_FOR [SOLVE_TYPE] [FLAGS]
Example(s):
>>> caspy eq x**x 2 x
>>> caspy eq sin(x)=1 x -st
评估
Evaluates an expression.
After expression you can also subtitute your variables with a value.
To substitute, simply type the variable to substitute followed by the value separated by a space.
For example:
>>> 3**(x+y) x 3 y 5
=> 3**((3)+(5))
=> 6561
Usage: eval EXPRESSION [VARS_SUB ... ] [FLAGS]
Example(s):
>>> caspy eval exp(pi)+3/sin(6)
>>> caspy eval 3**x x 3
实验
Expandes an expression.
Usage: exp EXPRESSION [FLAGS]
Example(s):
>>> caspy exp (a+b-c)**3
整数
Calculate definite and indefinite integrals of expressions.
Usage: caspy integ EXPRESSION VARIABLE {LOWER_BOUND UPPER_BOUND} [APPROXIMATE] [FLAGS]
Example(s):
>>> caspy integ 1/sqrt(1-x**2) x -1 1
>>> caspy integ x**x x -1 1 -A
限制
Calculate the limit of an expression.
Usage: caspy limit EXPRESSION VARIABLE AS_VARIABLE_IS_APPROACHING [SIDE] [FLAGS]
Example(s):
>>> caspy limit (1+1/(a*n))**(b*n) n oo
>>> caspy limit n!**(1/n) n 0 -
pf
Retreives the prime factors of an positive integer.
Note: exact_ans stores factors as dict: '{2: 2, 3: 1, 31: 1}'
while approx_ans stores factors as string: '(2**2)*(3**1)*(31**1)'
Usage: pf NUMBER
Example(s):
>>> caspy pf 372
simp
Simplifies an expression.
Usage: simp EXPRESSION [FLAGS]
Example(s):
>>> caspy simp sin(x)**2+cos(x)**2
启动
Start the GUI. No options/flags etc
总和
Calculate the summation of an expression.
Usage: caspy sum EXPRESSION VARIABLE START END [FLAGS]
\b
Example(s):
>>> caspy sum x**k/factorial(k) k 0 oo
>>> caspy sum k**2 k 1 m
系统均衡
Solves a system of either normal or differential equations.
Takes number of equations as argument, then will prompt user for all equations
Usage: sys-eq NO_OF_EQUATIONS [SOLVE_TYPE] [FLAGS]
Example(s):
>>> caspy sys-eq 5
>>> caspy sys-eq 3 -d Integers
网络
Choose a number from a list of usable maths websites and open it in default web browser.
type '-l' for a list of websites and enter a number. The website will be opened in the default browser.
Usage: web {NUMBER | LIST}
Example(s):
>>> caspy web 4
>>> caspy web -l
