Hello can I have some help here Section 11.2: 1-11 odd (first derivatives only)

EXERCISES 11.2 Tangents to Parametriza In Exercises 1-14, find an equation for the line tangent to the curve at the point defined by the given value of t. Also, find the value of day / dx2 at this point. 1. x = 2 cost, y = 2 sint, t = /4 2. x = sin 27t, y = cos 2nt, t = -1/6 3. x = 4 sint, y = 2 cost, t = 1/4 4. x = cost, y = V3 cost, t = 21/3 5. x = t, y = Vt, t = 1/4 6. x = sec2 t - 1, y = tant, t = -T/4 7. x = sect, y = tant, t = 1/6 8. x = - Vt+ 1, y = V3t, t =3 9. x = 212 + 3, y = 14, t=-1 10. x = 1/t, y = -2 + Int, t = 1 11. x = t - sint, y = 1 - cost, t = 1/3
