How do you know in which quadrant u work on!!!

[@MathematicsTutor]

Assume x to be an acute angle. That will help. Thanks

[@Lolafr-z5u]

@@MathematicsTutorthank you but what is an acute angle 😢

[@zainab-vz2bg]

hello. can you please explain how cos (x-3π /2) is in the third quadrant but sin (x-3π /2) is in the second quadrant? (as you showed in the quiz portion of the video)

[@MathematicsTutor]

will do later. Thanks

[@amyalexander7360]

Sir do you always assume the original angle is acute

[@amyalexander7360]

or does it specify in the exam

[@MathematicsTutor]

yes, we assume that to be acute angle
