solvefor t,cot(x)cot^2(x)=-1

解

解く

t, cot (x) cot^{2} (x) = - 1

解

すべての t で真; cot^{3} (x) = - 1

解答ステップ

cot (x) cot^{2} (x) = - 1

簡素化

cot (x) cot^{2} (x) : cot^{3} (x)

cot (x) cot^{2} (x)

指数の規則を適用する:

a^{b} \cdot a^{c} = a^{b + c}

cot (x) cot^{2} (x) = cot^{1 + 2} (x)

= cot^{1 + 2} (x)

数を足す:

1 + 2 = 3

= cot^{3} (x)

cot^{3} (x) = - 1

両側は等しい

すべての t で真; cot^{3} (x) = - 1

solvefor i,1-2sin^2(45-a/2)=sin(a)

so l v e f or i, 1 - 2 sin^{2} (4 5^{\circ} - \frac{a}{2}) = sin (a)

solvefor c,sin^2(x)+sin(x)-cos(x)+1/2 =0

so l v e f or c, sin^{2} (x) + sin (x) - cos (x) + \frac{1}{2} = 0

solvefor c,cos^4(s)-sin^4(x)+1+cos(x)=0

so l v e f or c, cos^{4} (s) - sin^{4} (x) + 1 + cos (x) = 0

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

so l v e f or c, cot^{2} (x) = cos (x) + sin (x)

solvefor y,y=sin(3t)u(t)*u(t)

so l v e f or y, y = sin (3 t) u (t) \cdot u (t)
