Sin t sin 3t sin 5t = 1/4(-sin t + sin 3t +sin 7t - sin 9t).

Step-by-step explanation:

Sin t . Sin 3t . Sin 5t = 1/4 [ - Sin t + Sin 3t + Sin 7t - Sin 9t ]

Take Right hand side and use the following formula

Take right hand side

Sin t . Sin 3t . Sin 5t

So, LHS = RHS

it has the same slope and a different y-intercept

hope this : )
