关于AP微积分计算器使用（TI-89 Titanium）
要考AP了,我的计算器是TI-89 Titanium
1.怎么用TI-89 算定积分
比如求y=x^2 在 （1,2）上的定积分
2.怎么求导
3.怎么求和 就是sum sigma的那个希腊字符
4.最大值最小值
注：我知道这些都在home里面的F3
就是不知道该怎么输入arguments（就是括号里该输什么,按什么顺序输,）
每次不是说too few arguments就是too many arguments,再不然就是argument should be a variable,expression云云.
非常烦躁!希望有高人帮下忙~

英语翻译
Stainless Steel,Titanium,Nickel,Nickel Alloys and certain Bronze parts are most
frequently processed by this method.Advantages include high production rates,
good permeability control and excellent dimensional reproducibility.
Part size and shape restrictions are those typical of P/M manufacturing process
as described in the MPIF Design Solutions Brochure.
2.Gravity Sintering;
Gravity or “loose powder” sintering is used to make porous metal parts from
powders that diffusion-bond easily (most production parts are made from
bronze).In this process,no outside pressure is applied to shape the part.The
appropriate material,graded for size,is poured into a mold cavity,which is a void
in the shape of the finished part.These metal particles are then heated to their
sintering temperature at which point a metallurgical bonding takes place,and
joining “necks” are formed at contact points.
Metallurgical Bonding
In consideration of the above process,the design engineer must,when
considering gravity sintering of a part,visualize the final shape completely
enclosed or surrounded by a mold,with the single exception of a “top” access
hole through which the cavity can be filled with powder.The formed shape that
can be easily extracted from that mold after it is sintered must also be visualized.
