Из уравнения sint + cost = 0,8 можно найти значения sin и cos.
cos = 0,8 - sint
Substitute cos back in to get the answer.sin * (0.8 - sin)
sin = 0.8 - cos.sin = 0.8 - (0.8 - sin)sin = 0.8 - 0.8 + sinsin = sin
sin cossin (0.8 - sin)sin * 0.8 - sin^20.8 sin - sin^2
Therefore, the answer is 0.8 sin - sin^2
Из уравнения sint + cost = 0,8 можно найти значения sin и cos.
cos = 0,8 - sint
Substitute cos back in to get the answer.
sin * (0.8 - sin)
sin = 0.8 - cos.
sin = 0.8 - (0.8 - sin)
sin = 0.8 - 0.8 + sin
sin = sin
sin cos
sin (0.8 - sin)
sin * 0.8 - sin^2
0.8 sin - sin^2
Therefore, the answer is 0.8 sin - sin^2
