Apprenez en ligne à résoudre des problèmes intégrales avec radicaux étape par étape. Integrate int((1-7w^2)^(1/2))dw. First, factor the terms inside the radical by 7 for an easier handling. Taking the constant out of the radical. We can solve the integral \int\sqrt{7}\sqrt{\frac{1}{7}-w^2}dw by applying integration method of trigonometric substitution using the substitution. Now, in order to rewrite d\theta in terms of dw, we need to find the derivative of w. We need to calculate dw, we can do that by deriving the equation above.

Final answer to the problem

$\frac{1}{2\sqrt{7}}\arcsin\left(2.6457513w\right)+\frac{2.6457513}{2\sqrt{7}}w\sqrt{1-7w^2}+C_0$
