Answer:
<u>In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. </u>
<u>The abbreviation is sin. sin θ = opposite / hypotenuse.</u><u>2 cosA sinB = sin(A + B) − sin(A − B) 2 cosA cosB = cos(A + B) + cos(A − B) 2 sinA sinB = cos(A − B) − cos(A + B)</u>
