`sin2x=2*sinx*cosx`Question: If cot(X) = 8/21 in quadrant-1, find sin (2x) =
What I did
Cot(X) = 8/21 = tan (X) = 21/8
I attached my work and I got 336/505 = 0.66547712
The question is asking me to give answers in decimal places!
I don't know what wrong I'm doing!
you used wrong identity for sin(2x)I don't know why is this wrong????
According to your previous calculations (response #2)What? I think it's right.
Sin2x = 2 * 8/√505 * 21/√505 =
Is this the correct form? Yes
The computer must be broken.Got it! The answer was .6653
The computer was not taking 0.6653 as a answer
