@theboombody Think of a wheel and choose a point on the wheel. imagine this point being in contact with the ground. imagine it spinning until the point is on the ground again. The distance moved by teh wheel will give us the circumference. If the radius is a half, the circumference will be Pi.
The quantities are related by the formula: length=(angle in radians)x(radius) so by calculatinig the circumference one is choosing 2Pi to be the angle. if we choose other unit, Pi will still be present.
A college poffessor asks his students ,"whats the difference between pi and phi . All of the students don't answer. The proffessor says ," phi is an H of a lot cooler than pi".

@acecf23 let u(1) be the fisrt term so that the three terms are given by, u(1)r^0, u(1)r^1 and u(1)r^2 respectivelly.
The third term is given by the u(1)r^2=3.2[u(1)+u(1)r] which implies that r^2=3.2(1+r) and consequently r^2-3.2r-3.2=0 and by solving the quadratic equation for r we yield:
r=-4/5; r=4
since r must be a positive integer greater than 0, r=4
The sum of the terms and is given by 42=u(1)[r+r^2]=u(1)[4+4^2]=20u(1) and therefore u(1)=21/10
thanks for helping me with my geometry homework

I kind of wish we used radians instead of degrees more often. I'm interested to see how an angle of pi is related to a distance of pi.

Can any one solve this problem for me.
A GEOMETRIC SERIES HAS THREE TERMS. THE SUM OF THE THREE TERMS IS 42. THE THIRD TERM IS 3.2 TIMES THE SUM OF THE OTHER TWO. WHAT ARE THE TERMS?

u(3)=168/5

I love these videos. I'm pretty sure most people out of highschool wouldn't know how to begin doing any of the things you demonstrate. :D
