Question: 7 If sin t =, and t is in quadrant I, find the exact value of sin (2t), cos(2t), and 9 tan (2t) algebraically

7 If sin t =, and t is in quadrant I, find the exact value of sin (2t), cos(2t), and 9 tan (2t) algebraically without solving for t. Enclose numerators and denominators in parentheses. For example, (a - b)/(1+ n). sin (2t)=56/81*sqrt(2) cos (2 t) = tan (2t) =
