Question

short tricks for integration​

Answer 1

Step-by-step explanation:

∫ cos ⁡ 2 x sin ⁡ x + cos ⁡ x d x = ∫ cos ⁡ 2 x − sin ⁡ 2 x sin ⁡ x + cos ⁡ x d x = ∫ ( cos ⁡ x − sin ⁡ x ) d x = sin ⁡ x + cos ⁡ x + C , \begin{aligned} \int\frac{\cos 2x}{\sin x+\cos x}\, dx &=\int\frac{\cos^2x-\sin^2x}{\sin x+\cos x}\, dx\\ &=\int(\cos x-\sin x)\, dx\\ &=\sin x+\cos x+C, \end{aligned} ∫sinx+cosxcos2 ...

Answer 2

Answer:

The best way to learn integration is to first study and then practice. Find a good calculus textbook, such as Thomas' Calculus, and first understand the conceptual ideas behind the integral and its relation to the derivative.
