a)
f'(x) = (x^2-6x+5)' = (x^2)' - (6x)' +5' = 2x-6 \ \ f'(x_0) = f'(2) = 2*2-6 = -2
б)
f'(x) = (sinx)' = cosx \ \ f'(x_0) = f'(- frac{ pi }{2} ) = cos(- frac{ pi}{2} ) = 0
в)
f'(x) = (3/x)' = (3x^{-1})' = 3 * (-1) * x^{-1-1} = -frac{3}{x^{2} } \ \ f'(x_0) = f'(-1) = -frac{3}{(-1)^{2} } = -3
г)
f'(x) = (1/2x^4+16x)' = (frac{1}{2} x^{4})' + (16x)' = frac{1}{2} * 4 *x^3 + 16= \ \ = 2x^3 + 16
д)
f'(x) = (x^3 - 12x + 36x + 1)' = (x^3)' - (12x)' + (36x)' + 1' = \ \ = 3 x^{2} -12 + 36 = 3 x^{2} +24
