Respuesta :

Ok I figured it out after several youtube videos
Use the rule:  a÷ b/c = a*c/b
= tan(3π*1/4)

Simplify 3π*1/4 to 3π/4
= tan(3π/4)

Simplify 
= -1                                                                                                                                   (the slash (/) means fraction not division) ex 4/2 is 4 over 2
