Answer

${dy}=\frac{3}{\sqrt{x}}\csc({1-2\sqrt{x}})\cot({1-2\sqrt{x}})){dx}$

Work Step by Step

We evaluate the function: $y=3\csc({1-2\sqrt{x}})$ on differentiating the above: $\frac{dy}{dx}=\frac{d(3\csc({1-2\sqrt{x}}))}{dx}$ or $\frac{dy}{dx}=-3\csc({1-2\sqrt{x}})\cot({1-2\sqrt{x}})\frac{d(({{1-2\sqrt{x}}})}{dx}$ or $\frac{dy}{dx}=\frac{3}{\sqrt{x}}\csc({1-2\sqrt{x}})\cot({1-2\sqrt{x}}))$ or ${dy}=\frac{3}{\sqrt{x}}\csc({1-2\sqrt{x}})\cot({1-2\sqrt{x}})){dx}$ The final answer is: ${dy}=\frac{3}{\sqrt{x}}\csc({1-2\sqrt{x}})\cot({1-2\sqrt{x}})){dx}$
