If sinc(x)=0.707.. what is x..
How do we calculate this
Thanks
You're asking how to solve $\displaystyle \frac{\sin (\pi x)}{\pi x} = 0.707 ..$. You can't get an exact value in closed form. It's an example of a transcendental equation.
If you're only interested in calculatiing a numerical approximation to the exact value, then there are many options.
