1. 3x - x^2 = F(b) - F(a) = (3*3) - (3*3) - ( 3 -1 ) = -2
2. 2 ∫ (От нуля до pi 2 ) sinx = 2 * (-cosx) = F(b) - F(a)
2 ( -cos(pi/2 ) + cos(0) ) = 2
Ответ : 2
3. ∫cosxdx = sinxdx = F(b) - F(a) = sin(π/2) - sin(0) = 1
Otvet : 1
4.1/3 ∫ d(3x-2)/ √3x-2 = 1/3 * (3x-2)^3/2 * 2/3 = корень(3*x-2)*(6*x-4)/9;
= F(b) - F(a) = 0
