Hey Ive got two questions regarding Cicular Functions, could you possibly include some working as I am really struggling with this topic:

I need to find the next four values for (t):

6=3sin(2t)+3

I know the first one is 5(pie)/4, i think the second is 9(pie)/4

and

between (pie) and 4(pie)

y=2sin(3t-(pie)/4)+8 for which y attains the minimum value.

thanks guys
