y = 2e^3x

When x = 1, y = 2e^3

Now, dy/dx
= 6e^3x
= 6e^3 when x = 1

Gradient of tangent is 6e^3
Gradient of normal is -1/(6e^3)

For the tangent,

y = 6e^3 * x + c
2e^3 = 6e^3 * 1 + c
c = -4e^3

Tangent: y = 6e^3 * x - 4e^3

For the normal,

y = -1/(6e^3) * x + c
2e^3 = -1/(6e^3) * 1 + c
c = 2e^3 + 1/(6e^3)

Normal:
y = -1/(6e^3) * x + 2e^3 + 1/(6e^3)
(6e^3)y = -x + 12 (e^3)^2 + 1
(6e^3)y = -x + 12e^6 + 1
