Given that sin(t) =0.3034 and t is in quadrant I, find sin(2t).

------------
There are no fraction or decimal quadrants. There are 4 of them - 1, 2, 3 & 4

Given that sin(t) =0.3034 and t is in quadrant I, find sin(2t).
Step 1, find the cos(t)
cos = sqrt(1 - sin^2) = 0.9079
---
Step 2, sin(2t) = 2sin(t)*cos(t)
