Answer:

m<3 = 97

m<10 = 97

m<9 = 83

m<5 = 97

m<7 = 83

m<16 = 97

Step-by-step explanation:

m<3 = m<2 because of vertical angles

m<10 = m<2 because of corresponding angles

m<9 + 97 = 180

m<9 = 83

m<5 + 83 = 180

m<5 = 97

m<7 = m<6 because of vertical angles

m<16 = m<5 because of alternate exterior angles.

Question attached as screenshot belowPlease help me with my calculus homework I am paying close attention

Wewaii [24]

Given:

$\int ^1_{-1}\frac{1}{x^2+1}dx$

To evaluate:

As we know,

$\int ^{}_{}\frac{1}{x^2+1^{}}dx=\tan ^{-1}(x)+C$

So, we have

$\begin{gathered} \int ^1_{-1}\frac{1}{x^2+1}dx=\tan ^{-1}(1)-\tan ^{-1}(-1) \\ =\frac{\pi}{4}-(-\frac{\pi}{4}) \\ =\frac{\pi}{4}+\frac{\pi}{4} \\ =\frac{2\pi}{4} \\ =\frac{\pi}{2} \end{gathered}$

Hence, the answer is,

$\frac{\pi}{2}$
