I need help with the following questions please.

Use the definition of Taylor series to find the first three nonzero terms of the Taylor series (centered at c) for the function f. f(x) = 3 tan x, c = 2n f ( x ) = XA projectile fired from the ground follows the trajectory given by the following equation, where vo is the initial speed, 0 is the angle of projection, g is the acceleration due to gravity, and k is the drag factor caused by air resistance. y = tan(0) + g x + g kx 1 KVo cos(0) K2 Vo cos(0) x 2 4 Using the power series representation In(1 + x) = X - + 2 3 4 + ...,-1
