公式输入符号

≈≡≠=≤≥<>≮≯∷±+-×÷/∫∮∝∞∧∨∑∏∪∩∈∵∴⊥‖∠⌒⊙≌∽√

+: plus(positive正的)

-: minus(negative负的)

*: multiplied by

÷: divided by

=: be equal to

≈: be approximately equal to

(): round brackets(parenthess)

[]: square brackets

{}: braces

∵: because

∴: therefore

≤: less than or equal to

≥: greater than or equal to

∞: infinity

LOGnX: logx to the base n

xn: the nth power of x

f(x): the function of x

dx: diffrencial of x

x+y: x plus y

(a+b): bracket a plus b bracket closed

a=b: a equals b

a≠b: a isn't equal to b

a>b : a is greater than b

a>>b: a is much greater than b

a≥b: a is greater than or equal to b

x→∞: approches infinity

x2: x square

x3: x cube

√ ̄x: the square root of x
