How do I express tan (-7?/4) in terms of ratios of acute angles? Is (-7?/4) equivalent to -315[sup:2cp4qity]o[/sup:2cp4qity]?

Seriously, I hope they mean the ratio sin(x)/cos(x), where x is an acute angle.
If so, then use the reference angle for -7?/4. After all, it's in Quadrant I, so x is acute.
Is -7?/4 equivalent to -315[sup:x8xtb95m]o[/sup:x8xtb95m]? Yes
Hey buddy, are you learning on your own or attending math classes?IloveManUtd said:How do I express tan (-7?/4) in terms of ratios of acute angles? Is (-7?/4) equivalent to -315[sup:3iwzz3m7]o[/sup:3iwzz3m7]?
