but I think it's motivational, and so I said, are you sure that J.R. Hicks invented the term "forward rate"?
但我觉得这很有趣,我问他,你能肯定,J·R·希克斯是"远期利率"的提出者吗
I'm going to just put that in, and it's the cosine of the number times i plus sine of the number times j times R.
我要在式子加入这个量,这个式子就等于这个值的余弦乘以 i,加上这个值的正弦乘以 j 再乘以常数 R
Then, I was talking it over with another graduate student and he said, well if you want to find out why don't you ask J.R. Hicks?
随后,我和另一位研究生讨到了此问题,他说,如果你想知道,干嘛不直接去问J·R·希克斯
And he said, I think it's J.R. Hicks.
他说,应该就是J·R·希克斯
If you are describing a particle with location R, the vector we use typically to locate a particle, R then R is just i times x + j times y, because you all know that's x and that's y.
如果你要描述一个位移为 R 的质点,这个矢量一般用表示质点 R 的位移,R 可表示为 i ? x + j ? y,显然你们都知道这段是 x,那段是 y
