If a= 60 b=30 verify that - sin (a - b) = (sin a x cos b) - (cos a x s

1.	If a= 60 b=30 verify that - sin (a - b) = (sin a x cos b) - (cos a x sin b)
Answer» Answer: its not EQUAL because Step-by-step EXPLANATION: SIN(60-30)=SIN30=1/2-----1 (sin 60cos 30)=√3/2√3/2=3/2 (cos60sin30)=1/21/2=1/2 3/2-1/2=2/2=1 -------2 so its not equal

If a= 60 b=30 verify that - sin (a - b) = (sin a x cos b) - (cos a x sin b)

Answer»

Answer:

its not EQUAL because

Step-by-step EXPLANATION:

SIN(60-30)=SIN30=1/2-----1

(sin 60*cos 30)=√3/2*√3/2=3/2

(cos60*sin30)=1/2*1/2=1/2

3/2-1/2=2/2=1 -------2

so its not equal
