прошуууу срооочно!!!умоляю

Answer 1

1.

y'=x^11+x^2+1

y'(-1)=-1+1+1=1

tgx=1  x=П/4

2. f'=3x-П/2+4sinx

    f'(П/6)=П/2-П/2+4*1/2=2

3. v=s(t)'=4t^3-4t

    v(t)=4*27-12=96

4. f'=12x-3x^2>0

]0;4[

5. f'=2cosx-sqrt(2)=0

cosx=sqrt(2)/2

x=+-pi/4+2pik

0<1/4+2k<=4

k=0;1

0<-1/4+2k<=4

k=1;2

x1=pi/4

x2=9pi/4

x3=7pi/4

x4=15pi/4
