Find sin when given cos

WebApr 14, 2015 · sinA = 12 13 cosA = 5 13 tanA = 12 5 Explanation: The basic trig functions are defined in a right-angled triangle as: sinθ = opposite hypotenuse cosθ = adjacent hypotenuse tanθ = opposite adjacent So, as … Websin α = 1 2 cos α. Squaring both sides gives sin 2 α = 1 4 cos 2 α = 1 4 ( 1 − sin 2 α). Or sin 2 α = 1 5. Similarly one sees that cos 2 α = 4 5. Thus the possibilities are sin α = ± 1 5, cos α = ± 2 5. We still have to show that these possibilities are possible. We know that there is α such that tan α = 1 2.
