If sin(t)=3/5 and t is in the second quadrant, and if cos(v)=3/5 and v is in the fourth quadrant, what is tan(t+v)?
***
sin(t)=3/5
cos(t)=-4/5
tan(t)=sin/cos=-3/4
..
cos(v)=3/5
sin(v)=-4/5
tan(v)-sin/cos=-4/3
..
tan(t+v)=(tan(t)+tan(v))/(1-tan(t)*tan(v))
=(-3/4)+(-4/3))/(1-3/4*-4/3)
=(-9/12)+(-16/12))/(1-1)
=(-25/12)/0=undefined
tan(t+v)=undefined
