After graphing the lines, the answer is (-3/4, 31/4)
Answer:

Step-by-step explanation:
Given the indefinite integral
, using the substitute
x = 4 sec(θ)...1
The integral can be calculated as thus;
First let us diffrentiate the substitute function with respect to θ
dx/dθ = 4secθtanθ
dx = 4secθtanθdθ... 2
Substituting equation 1 and 2 into the integral function we will have;
