Answer:

sin(2*36.86989765) and get .96 or 24/25

7/25

Step-by-step explanation:

Start by solving for P

sinP=3/5

take the arcsin or sin^-1 and get

p=36.86989765

Then multiply by 2 and take the sin and get

sin(2*36.86989765) and get .96 or 24/25

Then take cos(2*36.86989765)=.28 or 7/25

Answer:

Steps below

Step-by-step explanation:

sin P = 3/5

cos p = √1 - sin² P = 4/5

sin 2P = 2 * sin P * cos P = 2 * 3/5 * 4/5 = 24/25

cos 2P = cos² P - sin² P = 16/25 - 9/25 = 7/25
