1.	The tangent of the graph of the function y = f(x) at the point with abscissa x = 1 form an angle of π6 and at the point x = 2 an angle of π3 and at the point x = 3 angle of π4. The value of ∫31f′(x)f"(x)dx+∫31f"(x)dx(f"(x)) is suppose to be continuous) is
Answer» The tangent of the graph of the function y = f(x) at the point with abscissa x = 1 form an angle of $\frac{π}{6}$ and at the point x = 2 an angle of $\frac{π}{3}$ and at the point x = 3 angle of $\frac{π}{4}$ . The value of $\int_{1}^{3} f^{'} (x) f " (x) d x + \int_{1}^{3} f " (x) d x (f " (x))$ is suppose to be continuous) is
