ctgα = 1/√6 = √6/6
tgα = sinα/cosα
sin²α + cos²α = 1
sinα = √6 * cosα
(√6cosα)² + cos²α = 1
6cos²α + cos²α = 1
7cos²α = 1
cosα = 1/√7 = √7/7
sinα = √6 * √7/7 = √42/7

tgα = 2√2
ctgα = √2/4
2√2 = sinα/ cosα
sin²α + cos²α = 1
sinα = 2√2 cosα
(2√2 cosα)² + cos²α = 1
8cos²α + cos²α = 1
9cos²α = 1
cosα = ⅓
sinα = 2√2/3
