Given the curve y = 1 / 3x3 + 4 / 3 (1), find the tangent equation of the curve at point P (2,4) (2) find the tangent equation of the curve passing through point P (2,4)

Given the curve y = 1 / 3x3 + 4 / 3 (1), find the tangent equation of the curve at point P (2,4) (2) find the tangent equation of the curve passing through point P (2,4)

Derivation, y = X2,
When x = 2, y '= 4
Y = 4x-4. Passing (2,4) point
