In interrogative sentences, do verbs have the present progressive form
In the premise after the verb
I am cleaning the room. Are you cleaning the room
The following four functions are periodic functions
1.y=3
2. Y = 3x degrees
3.y=sin|x|,x∈R
4. Y = sin (1 / x), X ∈ R and X ≠ 0
One
The first one takes any number as a period
A y = TaNx b y = sin absolute value x C Y = cos2x d y = absolute value SiNx d y = absolute value SiNx
Is it necessary for the verb to change its original form when the present progressive declarative sentence becomes a special question
What are you doing?
Isn't it doing in the end?
It seems that we should not use the original shape
In the following functions, if the period is π and is a decreasing function on [π 4, π 2], then ()
A. y＝sin(2x+π2)B. y＝cos(2x+π2)C. y＝sin(x+π2)D. y＝cos(x+π2)
C. The period of the function in D is 2 π, so when x ∈ [π 4, π 2], 2x + π 2 ∈ [π, 3 π 2], y = sin (2x + π 2) is a decreasing function and y = cos (2x + π 2) is an increasing function
The verb be is reduced and changed into a general question
1.the pen's my brother's
2.that's liu's sister
3.Anna's Jim's sister
4.the pen's miss jin's
5.my mother's handbag's yellow and white
6.it's helen's grandma's glass
1.The pen is my brother's.
Is the pen your brother's?
2.That is Liu's sister.
Is that Liu's sister
3.Anna is Jim's sister.
Is Anna Jim's sister?
4.The pen is Miss Jin's.
Is this Miss Jin's pen?
5.My mother's handbag is yellow and white.
Is your mother's handbag yellow and white?
6.It is Helen's grandma's glass.
Is it Helen's grandma's glass?
1.Is the pen your brother's?

2.That is Liu's sister.->is this Liu's sister?
3.Anna is Jim's sister.-> is Anna Jim's sister?
4. The pen is Miss Jin's - > is the pen mis
1.The pen is my brother's.-> Is the pen my brother's?

Pay attention to the difference between the verb abbreviation be and the case of the noun
In R, of the following functions which are periodic are
A sin(e^x)
B e^sinx
C xcosx + tanx
D arcsinx + arccosx
Please explain the reasons
I started with D, but the answer was B
I don't understand. Please give me more advice
SiNx is a periodic function, so e ^ SiNx is also a periodic function
As for D, arcsinx + arccosx = Pai / 2 is a constant function, generally not a periodic function
More importantly, the domain of D is not r, but (negative divide by 2, divide by 2)
D is a constant function
How to change the present progressive into a general question? Does the general question begin with an auxiliary verb or a be verb?
Be verb in advance
If the minimum positive period of the following functions is 2 π
A.y=sin²x
B.y=sin|x|
C.y=|cos(x/2-π/3)|-1/2
D.y=sinx/1+cosx
A. Period π
B. Period π
C. Period 2 π
D. Period 2 π
D
D
Ta=π
Tb=π
Tc=4π
Didn't the teacher say that the minimum positive period of sin (NX) or cos (NX) is π / N, so you can get the answer by carefully deforming each option; the answer of option B can be obtained by drawing a picture
Good reading will do, come on. I almost forgot, ha ha
