Question

sin²4x + cos²4x =1 ???? dsooo

Answer 1

a math formula is sinsquare x+ cos square x=1
when the angle of sin and cos in this formula is equal than this is equal to 1

Answer 2

⏬⏬hey buddy,,,,,


Sin^2 4x+ Cos^2 4x= 1

we know that Sin^2tita+ Cos^2 tita= 1

here tita may be anything,,,, like 3x 2x 4x or π or 60' may be anything,,, or like
(a+b),,, there sum of square is always 1

i.e, (4x)= tita,,,

hence the guven statement is true
