The motion of an object is simple harmonic with equation of motion x = (27.1 m) sin(16.0 t /s + 0.7). At what time after t=0 will the displacement reach its first maximum (where velocity equals zero)?

help please? i only have the clue that it has to do with trigonmetry.

so wouldnt you set the sin(16.0 t /s + 0.7)=1 and solve for t?

1 = sin (16t + .7)

sin^-1 (1) = 16t + .7

... etc. sin^-1 is the sine inverse function.

Take the derivative and solve it for a zero.

^Yeah, I was going to tell him that, but the way Vitamin_A suggested works, too.
