___cosb=1/2[sin(a+b) + sin(a-b)

Bond [772]

Use the addition and subtraction theorem:

sin (A + B) = sin A + cos B
sin (A - B) = sin A - cos B

From there it's just a matter of simplification.

sin A cos B = 1/2 [ sin (A + B) + sin (A - B) ]
sin A cos B = 1/2 [ sin A cos B + cos A sin B + sin (A - B) ]
sin A cos B = 1/2 [ sin A cos B + cos A sin B + sin A cos B - cos A sin B ]
sin A cos B = 1/2 [ 2 sin A cos B ]
sin A cos B = sin A cos B

How do you divide factorials by lesser factorials again?

meriva

Answer:

(answer in explanation)

Step-by-step explanation:

so, whenever you divide factorials, as soon as you get it to be the same ! on the top and bottom of the fraction, they cancel out like any other fraction would.

So, lets say you're dividing 55! / 50!

55! can also be thought of as 55 x 54 x 53 x 52 x 51 x 50!

$\frac{55*54*53*52*51*50!}{50!}$ = 55 * 54 * 53 * 52 * 51

Then you can simply solve the remaining equation

( 55 * 54 * 53 * 52 * 51 = 417,451,320)

hope this helps!!
