Question

Could someone tell me the method to determine the measurements of angles in terms integrals of pi when sin(theta-pi/4) , cos(theta-pi/4) Also tell me the way and step of determination
general note:- Plz don't delete my question and answer asap)​

Answer 1

Answer:

Sin(45) cos(45)

Step-by-step explanation:

One pi is 180° in terms of angles, so pi/4 means 180/4 =45°.

You can apply the same for any angle
