tan^0(2x+15)=-1

解答

tan^{0} (2 x + 15) = - 1

无解

求解步骤

tan^{0} (2 x + 15) = - 1

使用法则

a^{0} = 1, a \neq = 0

1 = - 1

两侧不相等

无解

x = \frac{20}{sin ( 4 5 ^{\circ} )}

p ro v e sin^{4} (u) - cos^{4} (u) = 2 sin^{2} (u) - 1

p ro v e tan^{4} (x) - sec^{4} (x) = - 2 sec^{2} (x) + 1

p ro v e (tan (x) + cot (x)) tan (x) = sec^{2} (x)

p ro v e (cos (x) + sin (x))^{2} - 2 sin (x) cos (x) = 1
