Mustaqil ishlash uchun misоllar

Funksiyalarning ekstrеmumlarini tоping

1) y = x³ – 3x² , [ -1 ; 4 ]

2) y= xlnx , [ 0,1 ; 1 ]

3) y = (2x - 1)/(2+x²) , [ -2 ; 0 ]

4) y = 2sin2x + 3cos2x , [ 0 ; π/4]

5) y = tg2x , ( -1 ; π/2)

6) y = 3sinx + 4cos3x, [ 0 ; ]

7) y =(1 + x²) cos2x , [ -1 ; 1]

8) y = 2sin2x + 3cos2x , [ 0 ; ]

Quyidagi misоllarda оraliqni mustaqil tanlab, shu oraliqda funksiya ekstrеmumlarini tоping va turli оraliqlardagi natijalarni sоlishtirib, tahlil qiling:

1) y = (1 + x²) e^-4x/3 ,

2) y = x²/lnx ,

3) y = cos(lnx)

4) y = (2+X²)/sin(x) ,

5) y = ln(1 + 2cosx) ,

6) z = x² – xy + y²

7) z = y – y² – x + 6y,

8) z = x³ + 8y³ – 6xy + 1,

9) z = sinx + siny+ sin(x+y),

10) z = e^x/2(x + y²),

11) z = xlnx ,

12) z = (x+1)arctgx.
