solvefor t,v=311cos(30t+30)v

해법

을 위해 해결하다

t, v = 311 cos (30 t + 3 0^{\circ}) v

해법

t = \frac{18 0 ^{\circ} n}{15} - 1^{\circ} + \frac{1.56758 \dots}{30}, t = 1 2^{\circ} - 1^{\circ} + \frac{18 0 ^{\circ} n}{15} - \frac{1.56758 \dots}{30}

+1

라디안

t = - \frac{π}{180} + \frac{1.56758 \dots}{30} + \frac{π}{15} n, t = \frac{π}{15} - \frac{π}{180} - \frac{1.56758 \dots}{30} + \frac{π}{15} n

솔루션 단계

v = 311 cos (30 t + 3 0^{\circ}) v

측면 전환

311 cos (30 t + \frac{π}{6}) v = v

양쪽을 다음으로 나눕니다

311 v; v \neq = 0

311 cos (30 t + \frac{π}{6}) v = v

양쪽을 다음으로 나눕니다

311 v; v \neq = 0

\frac{311 cos ( 30 t + \frac{π}{6} ) v}{311 v} = \frac{v}{311 v}; v \neq = 0

단순화

cos (30 t + \frac{π}{6}) = \frac{1}{311}; v \neq = 0

cos (30 t + \frac{π}{6}) = \frac{1}{311}; v \neq = 0

트리거 역속성 적용

cos (30 t + 3 0^{\circ}) = \frac{1}{311}

일반 솔루션

cos (30 t + 3 0^{\circ}) = \frac{1}{311}

cos (x) = a \Rightarrow x = arccos (a) + 36 0^{\circ} n, x = 36 0^{\circ} - arccos (a) + 36 0^{\circ} n

30 t + 3 0^{\circ} = arccos (\frac{1}{311}) + 36 0^{\circ} n, 30 t + 3 0^{\circ} = 36 0^{\circ} - arccos (\frac{1}{311}) + 36 0^{\circ} n

30 t + 3 0^{\circ} = arccos (\frac{1}{311}) + 36 0^{\circ} n, 30 t + 3 0^{\circ} = 36 0^{\circ} - arccos (\frac{1}{311}) + 36 0^{\circ} n

30 t + 3 0^{\circ} = arccos (\frac{1}{311}) + 36 0^{\circ} n

해결 :

t = \frac{18 0 ^{\circ} n}{15} - 1^{\circ} + \frac{arccos ( \frac{1}{311} )}{30}

30 t + 3 0^{\circ} = arccos (\frac{1}{311}) + 36 0^{\circ} n
