Prove: cos(3x)=sin(2x)

Sagot :

Answer:

Step-by-step explanation:

Step-by-step explanation:

By taking ( x = 18°)

L.H.S

cos(3x)=sin(2x)

cos(3x) = cos( 3X18°)= cos (54°)

            = cos[ 90° - (2x18°)]           ∵[  90°- (2x18°) = 54°]

            = ∴ sin ( 2x18°)

      As (x = 18°)

            = sin (2x) = R.H.S
