SUMMARY

The integral problem presented involves the expression $$\int_{}^{}\frac{ds}{\sqrt{s^2-0.01}}$$. The discussion highlights the use of substitution methods to simplify the integrand, specifically recommending the substitution $s = r \sec(x)$, which utilizes the identity $\sec^2(x) - 1 = \tan^2(x)$. Additionally, the alternative substitution $s = r \cosh(t)$ is suggested, which transforms the differential to $\mathrm{d}s = r\sinh(t)\,\mathrm{d}t$, potentially leading to a more manageable form of the integral.

Hello can you help solve this problem

$$\int_{}^{}\frac{ds}{\sqrt{s^2-0.01}}$$

I tried using method of substitution but I still could not find a good cancellation.
Please tell me what to do. Thanks!

Integrals of that form can be generalized to
$$\int \frac{ds}{\sqrt{s^2-r^2}}$$

Using the substitution $s=r \sec\left({x}\right)$ simplifies the integrand because of the property $\sec^2\left({x}\right)-1=\tan^2\left({x}\right)$.

Trying this, what do you get?
 
The substitution $\displaystyle \begin{align*} s = r \cosh{(t)} \implies \mathrm{d}s = r\sinh{(t)}\,\mathrm{d}t \end{align*}$ may lead to a simpler integrand.
