I am having a problem w/ using mathematical induction to prove formal for all positive integers n. Please help. I have foiled and everything I am so confused. Thanks.
2^3 + 4^3 + 6^3 + ... + (2n)^3 = 2n^2(n+1)^2
Monochromatic light with a wavelength of 6.4 E -7 meter passes through two narrow slits, producing an interference pattern on a screen 4.0 meters away. The first order bright band lines are 2.0 E -2 meters away from the central bright maxima.
What is the distance between the slits?
1.3 E -4 m...
