I need help please for this Trig equation!
How do I do tan2x = -1 between -2pi<=x<=2pi ??
first find all values of 2x whose tan = -1 in the range -4pi to 4pi then divide by 2
first find all values of 2x whose tan = -1 in the range -4pi to 4pi then divide by 2
My values dont match the teachers, well my negative values dont
Yup okay so 3pi/4 and 7pi/4
the 2 values of x between 0 and 2pi are 4p-/4 and 7pi/4 - yes
can you help me find al the values though please
values of 2x are 3pi/4,7pi/4, 3pi/4 + 2pi, 7pi/4 + 2pi, -pi/4, -5pi/4, -pi/4 - 2pi, -5p i/4- 2pi ill let you simplify some of those values of x are half of these
values of 2x are 3pi/4,7pi/4, 3pi/4 + 2pi, 7pi/4 + 2pi, -pi/4, -5pi/4, -pi/4 - 2pi, -5p i/4- 2pi ill let you simplify some of those values of x are half of these
Thank you!! That's what I got too but thats not what my teacher did so I got confused!
