(cos A + cos b)^2 + (sin A + sin B)^2=?
emmasim [6.3K]
First, we expand the equation:

cos^{2}A+2cosAcosB+ cos^{2}B+sin^{2}A+2sinAsinB+sin^{2}B

Then, we combine certain terms in order to simplify them using trigonometry identities.

cos^{2}A+sin^{2}A+cos^{2}B+sin^{2}B+2cosAcosB+2sinAsinB

Note these identities:
Pythagoran relation: cos^{2}A+sin^{2}A = cos^{2}B+sin^{2}B=1
Sum and Difference Formula/Identities: cos(A-B) = cosAcosB+sinAsinB

Thus, if we apply these identities, the simplified equation would be:
2(cos(A-B))+2

Simplying further, the answer would be

2[cos(A-B)+1]

What is the arc length of the subtending arc for an angle of 72 degrees on a circle of radius 4? 8 4 5 16 5 8 5
german
You can calculate the arc lenght by using this formula: 
arc length = 2π*r*(A/360) , where A=angle of the arc. 

So for you it would be: 
arc length = 2π*4*(72/360) = 5.03

I hope that helped.
