When given the resultant vector, R , and the smallest angle, \theta , the horizontal component, R_{x} , is R \cos \theta , and the vertical component, R_{y}, is R \sin \theta .
1) Show that k(k!) = (k+1)!-k!
2) Find the largest power of 7 that is a divisor of 100!
3) Express using factorial notation:
a) 30 x 28 x 26 x...x 4 x 2
b) 29 x 27 x 25 x...x 3 x 1
Thanks!
