Question

y= -3/2 sin(0.2t +1.4) looking for amplitude, period and frequency

Answer 1

I'd think the period is also the frequency

Answer 2

what is it..

Answer 3

amplitude is 3/2
period is 2pi/.2

Answer 4

\(\large \bf y=-{\color{blue}{ \cfrac{3}{2}}}sin({\color{purple}{ \square }}t+1.4)\qquad {\color{blue}{ amplitude}}\qquad period\ \cfrac{2\pi }{{\color{purple}{ \square }}}
