It equals 6 21/79 aaaaaaa
Step-by-step explanation:
∫ dt / (cos²(t) ⁹√(1 + tan(t)))
If u = 1 + tan(t), then du = sec²(t) dt.
∫ du / ⁹√u
∫ u^(-1/9) du
9/8 u^(8/9) + C
9/8 (1 + tan(t))^(8/9) + C
The midpoint is
(-4+0) / 2, (7 + (-3))/ 2 The first one is x coordinate and 2nd is the y cood)
= (-2, 2) answer
