8 months agoI don’t know how much of a “tip” it is, but I like to use my cellphone’s camera as binoculars. Nowadays zooms can be very powerful and I use it regularly to read faraway signs, see details on distant structures and to see far things in general. The anti-shake software usually is enough, but if whatever I’m trying to read or look at is VERY far, I zoom in, hold my breath to snap a quick picture and then examine it calmly. I’ve found it to be very convenient, specially when traveling
It still equals 1, you can prove it without using fractions:
x = 0.999…
10x = 9.999…
10x = 9 + 0.999…
10x = 9 + x
9x = 9
x = 1
There’s even a Wikipedia page on the subject
