solvefor c,sin(x)-5cos(x)=sin^2(x)+5cos^2(x)

解答

求解

c, sin (x) - 5 cos (x) = sin^{2} (x) + 5 cos^{2} (x)

对所有 c 为真; sin (x) - 5 cos (x) = sin^{2} (x) + 5 cos^{2} (x)

求解步骤

sin (x) - 5 cos (x) = sin^{2} (x) + 5 cos^{2} (x)

两侧相等

对所有 c 为真; sin (x) - 5 cos (x) = sin^{2} (x) + 5 cos^{2} (x)

so l v e f or i, sin (x) + sin^{2} (x) + cos^{3} (x) = 0

y = 2 sin (cos (+ 0))

so l v e f or x, y = x + 2 arctan (p)

so l v e f or x, z = sin (x) + cos^{3} (y)

r = 1 - sin (0)
