Need help w/ 1000/pi = int[0,12] [1.75 sin(0.5x + pi/7) + p]^2

[veltricity]

I need to solve for p but having some trouble.

. . .\(\displaystyle \large{ \dfrac{1000}{\pi}\, =\, }\)\(\displaystyle \large{ \displaystyle \int_0^{12}\, \left[\, 1.75\, \sin\left(0.5x\, +\, \dfrac{\pi}{7}\right)\, +\, p\, \right]^2 }\)

I tried everything but it keeps coming up as an imaginary number! I know its because when I do the quadratic formula my b value is negative but maybe im approaching it wrong.

Any help would be much appreciated, thank you!

veltricity,

you're missing the "dx." For help, you need to type out or download all of your steps up
to the point that you're stuck.

To what, exactly, are you applying the Quadratic Formula?

When you reply, please include a clear listing of your steps so far, starting with what you got when you squared out the integrand, proceeding through what you got when you then integrated term by term, showing what you got as the evaluated value of the definite integral, and then whatever you did next.

Thank you!
