Hi folks,new to the forum and would like to start by asking for help in four trignometry questions,lol!
As the title says, I have to find all solutions within the given range, Ive been racking my brains all day and can't get anywhere. They are as follows:
8.2 tan 2x = 10 0< x <180
5 cos 8 ( θ - 16) = -13 0 < θ < 140
5 sin 6x = -2 0< x < π
50 sin (3 θ + π/6) = 30 0< θ <2.5
π = pi (it doesnt appear to be clear the way ive written it
any help would be highly appreciated.
