In order for metals to bond they need to loose electrons to ensure that they have a full outer shell and become positively charged. The positive cations (metal ions) are attracted to the negatively charged e...

cos(2x)=cos 2 (x)-sin 2 (x)=2cos 2 (x)-1 Therefore:cos(2x)/cos 2 (x)=(2cos 2 (x)-1)/cos 2 (x)=2cos 2 (x)/cos 2 (x) - 1/cos 2 (x)=2 - 1/cos 2 (x)=2 - sec 2 (x) Integral of sec 2 (x) = tan(x) Integral of 2 = 2...
