(c-1)*(c-2)=c^2+(-1+-2)c+(-1*-2)
=c^2-3c+2
The square root of pi is aproximately 1.7725.
The first five multiples of 5: 5,10,15,20,25
The first five multiples of 6: 6,12,18,24,30
23 is the sum of three other consecutive prime numbers, 5,7, and 11.
It is the first prime number showing this characteristic.
Also, the sum of the first 23 primes is 874, which is divisible by 23.
1/4*365=365/4=91.25
3+8(7+7n)=-37+8n
→59+56n=-37+8n
Add 37 to both sides
96+56n=8n
Subtract 56n to both sides
96=-48n
n=-2
3(2/5)=3*(2/5)=6/5
cos[sin^(-1)(-3/5)]=cos(-0.6435011087933)=4/5
-11-(-12)-(-15)= -11+12+15= 16
r^2=0.785
Root both sides
r=$${\sqrt{{\mathtt{0.785}}}}$$
So, r= 0.886002 or -0.886002
