(1) Y = sin (2 / 3) x, X belongs to R
(2) Y = 0.5cos4x, X belongs to R
Please do not use the formula of coefficient before t = (2pai) / X. please calculate it step by step
Let t = 2 / 3) X
Then y = sin T;
Taking t as the independent variable, the period of the function is 2pai;
So sin t = sin (T + 2pai)
So sin (2 / 3) x = sin [(2 / 3) x + 2pai]
=sin [ (2/3)( x +3pai) ]
For X, the period is 3pai

The average velocity of the first man-made satellite launched by our country around the earth is 7.12 kilometers per second. The analytic function of the distance s (kilometers) around the earth with respect to time t (seconds) is given
There is a pool with a capacity of 300 cubic meters. Let the flow rate of injected water be q (cubic kilometers per minute) and the time required to fill the pool be t (minutes). In this changing process, which variables are constants? Is q a function of T? If so, please write the analytic expression of Q with respect to t
Thank you. Is there an answer
① The analytical formula is s = 7.12t
② Time t and injected water flow Q are variables, and the capacity of the pool is constant
Yes, the analytic expression is
Q=300×10^(-3)/T
S=7.12*T
Variable time, constant is the capacity of the pool, is, q = 300 / T
1.S=7.12*T
2. QT are all variables, one of which can be used as an independent variable and the other as a dependent variable, and the capacity 300 is a constant
Q is a function of T, QT = 300
So the analytical formula is q = 300 / T

Function. It should be very simple
As shown in the figure, the known function y = ax ^ 2 + BX passes through points a (- 3, - 3) and P (T, 0), and t is not equal to 0
(1) If t = - 4, find the value of a and B
(2) Write directly a value of t that makes the opening of the parabola downward
Mainly the first question
-3 = 9a-3b, 16a-4b = 0
Because the image of the function passes through a, B has - 3 = 9a-3b, 0 = 16A + 4B
Then a = - 1 / 7, B = 4 / 7
What does the present progressive tense mean in English? Who can help explain it?
In addition to expressing the future, the present continuous tense can also express the future. The present continuous tense is often used to express the future tense with the meaning of "intention", "arrangement" or "intention". This kind of present continuous tense is more vivid and gives people a sense of expectation. It is often used to express the recent or near future, and the verbs used are mostly transferred words
(1) I'm going
(2) I'm coming
(3) When are you starting?
The present continuous tense of the future can also be used in some non transitive verbs
(1) I'm meeting you after class
(2) What are you doing next Sunday?
(3) She is buying a new bike soon
But occasionally, it also indicates the far future
When I grow up, I'm joining the army
The present continuous tense of the future sometimes means "determination", which is often used in the negative structure
(1) I'm not going
(2) I'm not waiting any longer
Sometimes it is also used in affirmative construction
I'm backing out
Speaking with the other person in the present continuous tense can become an order, but the tone is mild
(1) You are staying
(2) Don’t forget:you are Take part too
Like the present tense, the present continuous tense can also express the future in adverbial clauses of time, condition or cause
(1) When you are passing my way, please drop in
(2) If they are not doing it, what am I to do
(3) She is going to the dentist tomorrow because she is having a tooth filled.
The present continuous tense can also be used in indirect speech to show that the speaker believes it will be true
He said he is going tomorrow
The present continuous tense of the future is sometimes subordinate to the future tense
(1) On election night we'll be telling you what's happening in various places in this country
(2) When I have time, I'll come down to the school to see how you're both doing
He said he________ me a present unless I_______ in doing the experiment.

The future tense is usually not used in time, condition or concession subject clauses
(2) Indicate the future events, itinerary and other activities that have been arranged now

Among the following four functions, the one with π as the minimum positive period and a decreasing function on the interval (π 2, π) is ()
A. y=2|sinx|B. y=sin2xC. y=2|cosx|D. y=cos2x
The minimum positive period of y = 2 | SiNx | is π, and it is a decreasing function in the interval (π 2, π), so option a is correct; the minimum positive period of y = sin2x is π, and it decreases monotonically in (π 2, 3, π 4), and increases monotonically in (3 π 4, π), so option B is incorrect; the minimum period of y = 2 | cosx | is π, and it is an increasing function in the interval (π 2, π), so option C is incorrect; the minimum period of y = cos2x is π, It is an increasing function in the interval (π 2, π), so option D is incorrect
