(x^3-3x^2+5x)'=3x^2-6x+5\ (x^4-8x^2-9+log_2x = x^4-8x^2-9+frac{ln x}{ln2})'=\ =4x^3-16x+frac{1}{ln 2}frac{1}{x}

 

int_2^3 x^3 dx = frac{x^4}{4} |_2^3 = frac{3^4}{4} - frac{2^4}{4} =frac{81-16}{4}= frac{65}{4}

 

int_0^1(3x+e^x)dx = frac{3}{2}x^2+e^x |_0^1=\ frac{3}{2}*1^2+e^1 - frac{3}{2}0^2 -e^0= frac{3}{2} +e -1 =e +frac{1}{2}

 

y'=(x^2-frac{1}{2}x^2)'=(frac{1}{2}x^2)'=2*frac{1}{2}x=x\ y'(2)=2\ y'(-2)=-2
