0.102 cos (3.715 t) = 0.82

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

0.102 cos (3.715 t) \cdot 1000 = 0.82 \cdot 1000

Simplificar

102 cos (3.715 t) = 820

102 cos (3.715 t) = 820

Dividir ambos lados entre

102

102 cos (3.715 t) = 820

Dividir ambos lados entre

102

\frac{102 cos ( 3.715 t )}{102} = \frac{820}{102}

Simplificar

cos (3.715 t) = \frac{410}{51}

cos (3.715 t) = \frac{410}{51}

sin^{2} (x) + 0.49 = 1

6 cos^{2} (θ) + sin^{2} (θ) = 4

15 sin (3 0^{\circ}) = 10 sin (x)

sin (0) = - sin (o) cos (0)

\frac{sin ( 78.0538888 9 ^{\circ} )}{8} = \frac{sin ( x )}{10}
