Find the gradient of the tangent to: a f(a) = sin z at the point where = 2T 3 b f()= cos a sin z at the point where =

Answer 1

2T 3

a) The gradient of the tangent to f(a) = sin z at the point where a = 2T 3 is -cos(2T 3).

b) The gradient of the tangent to f(a) = cos a sin z at the point where a = 2T 3 is -cos(2T 3)cos(2T 3).
