$\displaystyle\\1)f(x)=x^6+\frac{7}{x^6}-4\cos(x) \\\\\\F(x)=\frac{x^7}{7}+7*(-\frac{1}{5x^5})-4\sin(x)+C=\frac{x^7}{7}-\frac{7}{5x^5}-4\sin(x)+C\\\\\\2)f(x)=4\cos(5x-3)\\\\F(x)=4*\frac{1}{5}\sin(5x-3)+C=\frac{4\sin(5x-3)}{5}+C\\\\\\3)f(x)=(4+7x)^9\\\\F(x)=\frac{1}{7}*\frac{(4+7x)^{10}}{10}+C=\frac{(4+7x)^{10}}{70}+C$
