solvefor t,4.6=0.106cos(4.36t)

解答

求解

t, 4.6 = 0.106 cos (4.36 t)

解答

t \in R 无解

求解步骤

4.6 = 0.106 cos (4.36 t)

交换两边

0.106 cos (4.36 t) = 4.6

在两边乘以

1000

0.106 cos (4.36 t) = 4.6

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere are

3

digits to the right of the decimal point, therefore multiply by

1000

0.106 cos (4.36 t) \cdot 1000 = 4.6 \cdot 1000

整理后得

106 cos (4.36 t) = 4600

106 cos (4.36 t) = 4600

两边除以

106

106 cos (4.36 t) = 4600

两边除以

106

\frac{106 cos ( 4.36 t )}{106} = \frac{4600}{106}

化简

cos (4.36 t) = \frac{2300}{53}

cos (4.36 t) = \frac{2300}{53}

- 1 \leq cos (x) \leq 1

t \in R 无解

sin (x) = \frac{23}{24}

5-5cos(x)=4sin^2(x)

5 - 5 cos (x) = 4 sin^{2} (x)

3cot^2(x)-14csc(x)-2=0

3 cot^{2} (x) - 14 csc (x) - 2 = 0

250=100*5*cos(x)

250 = 100 \cdot 5 \cdot cos (x)

tan(x)= 1/(sin(2x)),0<= x<= pi

tan (x) = \frac{1}{sin ( 2 x )}, 0 \leq x \leq π
