u got or should I explain in my way?

 

[Haya Ahmed]

u got or should I explain in my way?

Nahh I got it !

 

[Thought blocker]

Nahh I got it !

Then too.. covert m cubed to m That's that I guess u might have not got.. I missed that step n was waiting for u to ask

prove tan^2(x) + cos^2(x) = sec^2(x) + (cos2x/2) - (1/2)

prove tan^2(x) + cos^2(x) = sec^2(x) + (cos2x/2) - (1/2)

Are you sure this is the correct equation? If yes, where did you find this question?

Q5 (ii) please someone explain it

 

[sara kamal]

guys i dont know which sign to put while its asked (in which interval f(x) is increasing and decreasing...please explain through these questions
1. 32x^2 - 2x^4
2 x^3 - 3X^2 +3X - 1

PLEASE LET ME KNOW AS SOON AS POSSIBLE

I don't know.

(Question related to M1)
Two equal forces: R= (2) (F1) (cos(theta/2)) (note: F1=F2)
can anyone explain how did the normal cosine rule change to this form when we have 2 equal forces ?

Hello. Im currently studying applications to differentiation and a question came out in which I have doubts about:
A curve is such that dy/dx= x^1/2 - x^-1/2
The curve passes through the point (4, 2/3)

Question: Find the coordinates of the stationary point and determine its nature.

I know that I have to equal the derived function to 0 however I don't know how to find the x-values, some basis that I have a lack with.
Can someone help me out plz?

Thank you

Do you have S1 doubts? I haven't done M1

 

[Haya Ahmed]

Do you have S1 doubts? I haven't done M1

Nah I take M1

 

[The Sarcastic Retard]

Nah I take M1

Though I will try.

 

[The Sarcastic Retard]

Nah I take M1

Okay I got the answer this is easy. I will PM you the answer.
