solvefor x,T(6)=3.15cos(pi/6 x)+19.15

Solución

resolver para

x, T (6) = 3.15 cos (\frac{π}{6} x) + 19.15

Solución

x = \frac{6 arccos ( \frac{120 T - 383}{63} )}{π} + 12 n, x = - \frac{6 arccos ( \frac{120 T - 383}{63} )}{π} + 12 n

Pasos de solución

T (6) = 3.15 cos (\frac{π}{6} x) + 19.15

Intercambiar lados

3.15 cos (\frac{π}{6} x) + 19.15 = T \cdot 6

Multiplicar ambos lados por

100

3.15 cos (\frac{π}{6} x) + 19.15 = T \cdot 6

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

2

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

100

3.15 cos (\frac{π}{6} x) \cdot 100 + 19.15 \cdot 100 = T \cdot 6 \cdot 100

Simplificar

315 cos (\frac{π}{6} x) + 1915 = 600 T

315 cos (\frac{π}{6} x) + 1915 = 600 T
