Help with cal 2 exercise involving integrals?
zhannawk [14.2K]

\displaystyle\int\frac{\sqrt{x^2+1}}x\,\mathrm dx=\int\frac{\sqrt{\tan^2B+1}}{\tan B}\sec^2B\,\mathrm dB

\tan^2B+1=\sec^2B

\sqrt{\sec^2B}=\sec B (provided that \sec B>0)

Then

\dfrac{\sec B}{\tan B}\cdot\sec^2B=\dfrac{\sec^2B}{\tan B}\cdot\sec B

(just moving around a factor of \sec B)

\dfrac{\sec B}{\tan B}\cdot\sec^2B=\dfrac{\sec^2B}{\tan^2B}\cdot\sec B\tan B

(multiply by \dfrac{\tan B}{\tan B})

Need help asap please
Gelneren [198K]

Answer:

31°

Step-by-step explanation:

<Y + <X = 180° [being co-interior angles ]

s + 91° + 2s - 4° = 180°

3s + 87° = 180°

3s = 180° - 87°

3s = 93°

s = 93° /3

s = 31°

Hope it will help you :)❤
