If you know the derivative of some function
, you can tell exactly who
is, up to an additive, constant term. In fact, knowing
, you have
In your case, we have
So, the integral is almost immediate:
So, up to some constant additive term, our function is
To fix this constant, we know that the function passes through the point (6,10), so we have
And so our function is
If we want to know when this function equals 6, we simply have to ask and solve for x, so we have

Step-by-step explanation:
<u>Complex Numbers</u>
They are expressed as the sum of a real part and an imaginary part:
Complex numbers can also be expressed in polar form:
Where r is the modulus of the complex number and θ is the argument.
The argument can be calculated by:
The angle θ must be calculated in the appropriate quadrant depending on the signs of the real and imaginary parts.
The complex number is given as:
Here: a=-3, b=-9
Since both components are negative, the argument lies in the third quadrant (180° < θ < 270°).
The calculator gives the answer 71.6°, we need to adjust the angle to the third quadrant by adding 180°, thus
