Question

heyo~

prove.



sin(a-b) = sina • cosb - cosa • sinb

Answer 1

Answer:

We know that cos (90-theta)=sintheta

putting theta =A-B, we get

sin(A-B)=cos{90-(A-B)}

=cos {(90-A)+B}

=cos(90-A) cosB-sin(90-A)sinB

Therefore, sin(A-B)=sinAcosB-cosAsinB

{Because,cos(90-theta)=sin,sin(90-theta)=costheta}

This is the proof of your question

hope it help you.

Thank you

Answer 2

tokyo ghoul was great and the anime opening song unravel was awesome but to be honest

it lost its quality after first season

kaneki vs Jason was epic

I reccomend you to watch demon slayer and one punch man as these 2 anime are good for those who are new to anime
