Дано sin альфа =0,6 найти cos tg и ctg

[latex]sin ^{2} alpha +cos^{2} alpha =1[/latex][latex]cos alpha = sqrt{1-sin^{2} alpha } = sqrt{1-0.6^{2}}=0.8 [/latex][latex]tg alpha = frac{sin alpha }{cos alpha } = frac{0.6}{0.8}=0.75 [/latex][latex]ctg alpha = frac{cos alpha }{sin alpha } = frac{0.8}{0.6}=1 frac{1}{3} [/latex]
