Y = SiNx + cosx 2. Y = SiNx · cosx + cosx 3. Y = SiNx + cosx - SiNx · cosx Better have a way!
First question y = SiNx + cosx = 1-cosx + cosx = - [(cosx-1 / 2) ^ 2-5 / 4] because - 1=
y=sinx/2-cosx
The root sign Y = SiNx / 2-cosx y = √ (3) / 3 (√ (3) / 2sinx - √ (3) cosx) y = √ (3) / 3 (cos30 * sinx-sin30 * cosx) y = √ (3) / 3sin (X-30) 30 is 30 degree, which cannot be marked
The minimum positive period of F (x) = (cosx + SiNx) / (cosx SiNx)
Division of cosx
(1+TANX)/(1-TANX)=TAN(π/4+x)
Who gave me 20 words with OO long vowels and 20 words with OO short vowels
Short vowels: book, cook, look, hook, took
Food of wood
What are the words of long vowel: [oi]. At least 5. What are the words of short vowel: [O]. At least 5
Thought about short talk hall for floor
Short: not hot got box tomorrow
Are there more words with long vowels or short vowels in English
Are the five vowels the same
Please give me the words in the common case of less than one
Please make your question more detailed. I don't understand what you asked. Of course, the pronunciation of five vowels will be different. In different words, their pronunciation is regular, but not absolute
Find short vowel examples (inverted E),
The more examples, the better. Thank you very much

Is there a vowel pronunciation of a, e, I, O, u in all words? Why
We just learned how to change the comparative and superlative levels of regular adjectives. One of the irregular changes is that the words ending with auxiliary elements should be written in double, and then er or EST should be added. We asked how to judge the auxiliary elements behind the adjectives. The teacher said that as long as a e IO u is a vowel, the other is a consonant, and the adjective Dity I is a e io According to the teacher, as long as these five are vowels, I am clearly a consonant when I read the phonetic alphabet!
No, for example, O in one, umbrella, u in useful are not
Phonetic symbols of vowels a e i o u take words as examples
late [leit]
evening [ˈi:vniŋ
ice [ais]
though [ðəu]
tune [ tju:n ]
