2k\pi +2\pi =\left(2k+2\right)\pi
Use the distributive property to multiply 2 by k+1.
2k\pi +2\pi =2k\pi +2\pi
Use the distributive property to multiply 2k+2 by \pi .
2k\pi +2\pi -2k\pi =2\pi
Subtract 2k\pi from both sides.
2\pi =2\pi
Combine 2k\pi and -2k\pi to get 0.
\pi =\pi
Cancel out 2 on both sides.
k\in \mathrm{C}
This is true for any k.
2k\pi +2\pi =\left(2k+2\right)\pi
Use the distributive property to multiply 2 by k+1.
2k\pi +2\pi =2k\pi +2\pi
Use the distributive property to multiply 2k+2 by \pi .
2k\pi +2\pi -2k\pi =2\pi
Subtract 2k\pi from both sides.
2\pi =2\pi
Combine 2k\pi and -2k\pi to get 0.
\pi =\pi
Cancel out 2 on both sides.
k\in \mathrm{R}
This is true for any k.
