A weight is attached to the end of a spring. Its height after t tt seconds is given by the equation h ( t ) = 5 − 2 sin ⁡ ( 2 π ( t + 1 ) 7 ) h(t)=5−2sin( 7 2π(t+1) )h, left parenthesis, t, right parenthesis, equals, 5, minus, 2, sine, left parenthesis, start fraction, 2, pi, left parenthesis, t, plus, 1, right parenthesis, divided by, 7, end fraction, right parenthesis. When does the weight first reach its maximum height? Give an exact answer.
