$\frac{\sqrt{1+0\sin\left(0\right)-\sqrt{\cos\left(2\cdot 0\right)}}}{\tan\left(\frac{0}{2}\right)^2}$
Learn how to solve problems step by step online. Find the limit of ((1+xsin(x)-cos(2x)^(1/2))^(1/2))/(tan(x/2)^2) as x approaches 0. Evaluate the limit \lim_{x\to0}\left(\frac{\sqrt{1+x\sin\left(x\right)-\sqrt{\cos\left(2x\right)}}}{\tan\left(\frac{x}{2}\right)^2}\right) by replacing all occurrences of x by 0. Multiply 2 times 0. Divide 0 by 2. The sine of 0 equals 0.
