solvefor i,sin(x)+sin^2(x)+cos^3(x)=1

解答

求解

i, sin (x) + sin^{2} (x) + cos^{3} (x) = 1

对所有 i 为真; sin (x) + sin^{2} (x) + cos^{3} (x) = 1

求解步骤

sin (x) + sin^{2} (x) + cos^{3} (x) = 1

两侧相等

对所有 i 为真; sin (x) + sin^{2} (x) + cos^{3} (x) = 1

x (15) = 0 + 705 \cdot 15 \cdot cos (2 5^{\circ})

so l v e f or t, 4 r + 12 s + 9 t = e^{3} x - 2 y + x y + cos (2 x + 3 y)

so l v e f or i, 5 sin (x) - 2 = 3 (1 - sin (x)) tan^{2} (x)

so l v e f or y, (b) y = e^{5 x} tan (x^{2} + 2)

\frac{1}{1} + tan (x) + \frac{1}{1} - tan (x) = 4
