Problem Solving Math
Use the approach in Gauss's Problem to find the following sums (do not use formulas) b. 1 + 3 + 5 + 7 +..... + 1001 Clearly the first number is 1, and last number is 1001, and the increment is 2. This a plug n chug. yes but, i will have to use a formula that way - 3*+2+2/-2^2

trig--power reducing formulas
You have to use doubling formulas again to express it in terms of cos(3x). If you know about complex numbers then the derivation is easy: cos(x) = [exp(i x) + exp(-i x)]/2 cos^3(x) = 1/8 [exp(3 i x) + exp(-3 i x)+ 3 exp(ix) + 3 exp(-ix) ] = 1/4 cos(3 x) + 3/4 cos(x)
