(1 + 2 times root 3 + root 5) / (1 + root 3) (root 3 + root 5) ---- simplification

The original formula is 1 / (root 3 + root 5) + 1 / (root 3 + 1) = (root 5-3) / 2 + (root 3-1) / 2 = (root 5-1) / 2) / 2

Simplify the value of 1 / 1 + root 2 + 1 / root 2 + root 3 +... + 1 / root 99 + root 100

1 / (1 + 2 + 2) + 1 / (1 + 2 + 2) + 1 / (1 + 2 + 3 + 3) +. Use square difference to solve 1 / (1 + 2 2 2) = ((2-1) / (2-1) (1 + 2-1) (1 + √ 2) = (2-1) / (2-1) (1 + 2-1) (1 + 2-2) = (2-11) / (3-3-2) (2) (2 + 3-3) = 3-3-2. The next one is 1 / 3-3-2, and the next one is 1 / 3-3 + 4 = 4-4-3-31 / 4 (4 + 4 + 5) = 5-5-5-4 / 4 / 4 / 4 / 5 = 5-5-5-5-5-5-5-5-5-5-4 / 41 / (5 +

Simplify root sign (1 + sin10) ten root sign (1-sin10)

sin10=2sin5cos5
The original formula = √ [(sin5) ^ 2 + (cos5) ^ 2 + 2sin5cos5] + √ [(sin5) ^ 2 + (cos5) ^ 2-2sin5cos5]
=√[(sin5+cos5)^2+√[(cos5-sin5)^2
