X plus y equals z X minus y equals z X times y equals z X divided by y equals z x除以y等于z X plus/minus/… is NOT equal to z X加/减/...不等于z The natural log of x equals y x的自然对数等于y X to the power of y equals z X的y次幂等于z Ln(x), x^y, … is NOT equal to z ....不等于z Put everything in parentheses, and then take the factorial. 所有东西放括号里，然后求阶乘 Take the integral – the bounds are from a to b 求函数在区间[a,b]上的定积分 Take the derivative 求导 Take the partial derivative of G with respect to T 求函数G关于变量T的偏导数 P has no effect on the final answer, since our system is in equilibrium P对最后结果没有影响，因为系统是守恒的(perhaps you should specify the system. Otherwise I can't ensure this one is right)

Credit for today's worksheet will be based on completeness, not accuracy. Credit for today's worksheet will be based on participation, not completeness. Hey, do you have a partner? Do you want to be partners? Do you mind if I join your group? Put everything in parentheses, and then take the factorial. Did you solve the problem? How did you solve this equation? Take the integral – the bounds are from a to b----------------------------------计算由（从）a到b的定积分 Take the derivative----------------------------计算导数 Take the partial derivative of G with respect to T-------------------------------计算函数G关于T的偏导数 P has no effect on the final answer, since our system is in equilibrium. ----------------因为（这里的）系统是一个恒等运算(not sure about this part)，所以P对结果没有影响
