expand 74sin(120pi(t-7/36))

expand

74 sin (120 π (t - \frac{7}{36}))

74 (- \frac{1}{2} sin (120 π t) + \frac{3}{2} cos (120 π t))

Solution steps

74 sin (120 π (t - \frac{7}{36}))

Expand

120 π (t - \frac{7}{36}) : 120 π t - \frac{70 π}{3}

= 74 sin (120 π t - \frac{70 π}{3})

Rewrite using trig identities

= 74 (- \frac{1}{2} sin (120 π t) + \frac{3}{2} cos (120 π t))

\frac{100 ( x ^{2} + 10 x + 100 )}{( x + 10 ) ^{2}}

- (\frac{2 ^{3}}{3}) - (\frac{2 ^{2}}{2}) + 12

P (1, - 2) y Q (3, 4)

\frac{( 3 - 5 + x ) ( 2 + 8 - x )}{x - 4}
