Trig Identities: cos^2(2x) + sin^2(2x), os^2(x)-1/sin(x),以前福斯的車友換了新車Infiniti Q50,近日相約去試乘了一下,坦白說之前日系車款一直無法列入口袋名單中,可能就是對歐系車的迷思,一直覺得那是品質保證,但~每次維修或是保養起來花費也是挺可觀,這次,試乘下來我真的完全改觀,從裡到外真的好的無可挑剔,讓原先還在猶豫是否要換雙B車款的我,馬上踩了煞Too bad your notation is not clear enough. If you mean for the entire expression to be in the numerator, you will need to write it like this: [cos^2(x)-1]/sin(x) = [1-sin^2(x)-1]/sin(x) = -sin^2(x)/sin(x) = -sin(x) And, really, what do you have against th...
