How do you make y= sin(sqrt(5x + 3)) in terms of y? :/

    1. Yes, I don't know this. =.=

    So how to you move sine to the y side?

    You can't say: arcsin(y) = sqrt(5x + 3), can you...?

    I don't know how to move the sin!
    Help!
    Thank you! :)

    You can do that as long as you realize it will only be valid for -pi/2<=sqrt(5x+3)<=pi/2.

    Hi Lo.Lee.Ta.! :smile:

    Generally, the equation
    $$y=sin(\theta)$$
    is equivalent to
    $$\theta=\arcsin(y)+ 2k\pi \quad \vee \quad \theta=\pi - \arcsin(y) + 2k\pi$$
    where ##k## is an integer and ##\theta## is an angle in radians.
