The sum of two logarithms is equal to the logarithm of the product, and the difference equals the quotient: log(A)+log(B)-log(C) =log(AB/C) Twice the logarithm of a quantity is the logarithm of the square of the quantity: 2log(C)=log(C²) So if we put it all together, we g...

Ways to get a sum of six =|{(1,5),(2,4),(4,2),(5,1)}| = 4 ways given that doubles are not rolled, therefore (3,3) was absent. Total number of ways: 6 faces * (6-1) faces to eliminate doubles = 30 So probability of rolling a total of 6 = P(6) = ?

Multiply both numerator and denominator by the conjugate, (1+sin(a)-cos(a)) To reduce typing, will use s=sin(a), c=cos(a), so (1+sin(a)- cos(a))/(1+sin(a)+cos(a)) =(1+s-c)/(1+s+c) =(1+s-c)²/((1+s+c)(1+s-c)) =(1+s²+2s+c²-2c(1+s))/((1+s)²-c²) now use s&s...
