y = xarcsinx/2 SQR (4-X^2), ask for dy. High number to take the exam. Begging online. Can add scores.
Zhkkk said so great. I completely mastered the trick of this question. Step by step: Arcsinx/2 x · 1/[SQR (4-X^2)] -X · 1/[SQR (4-X^2)], the last two items are available, and the final solution: dy = Arcsinx/2. Thank you zhkkk. I will give you 30 wealth currency.
