Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.
or
using a^2 - b^2 =(a+b)(a-b)
= sin(2x+x)sin(2x-x)
= sin 3x sin x
Answer:
<u>The probability that the first card is gray and the second card is pink= 5/78</u>
Step-by-step explanation:
A deck of cards has a 5 pink, 2 gray, And 6 black cards.
The total cards = 5 + 2 + 6 = 13
You pick two cards from the deck without replacement.
The probability that the first card is gray = 2/13
The remaining cards = 13 - 1 = 12
The probability that the second card is pink = 5/12
So,
The probability that the first card is gray and the second card is pink =
= 2/13 * 5/12 = 10/156 = 5/78
