Solve the following equation; domain 0 </= x </= 360; tan2 B = 4
63
117
243
297
select all that apply.
I think this is supposed to be:
tan^2 (B) = 4 if so........take the square root of both sides
tan (B) = [+/- ] 2
tan (B) = -2 at about 117° and at about 297°
And
tan (B) = 2 at about 63° and at about 243°
Check all the apply:
Wouldn't it be..
-63
-243
-117
