2x = 4 sec t
x = 2 sec t
How can I proceed? I don't think there's an identity to simplify sec^2 t - 1.
Right so I have;
4 (tan x + x) + C
Now I've got to construct that triangle. Since originally my x = 2 sec t, it becomes sec t = x/2. If we're looking for the cos it becomes cos t = 2/x. So on the triangle, the hypotenuse is x while the two sides are 2 and
But it's wrong apparently...
