any idea how to do this...? No measurementes
I hav no idea how to begin....

a sector of a circle with a central angle (Theta). Let A(Theta) be the area of the segment between the chord PR and the arc PR. Let B(Theta) be the area of the triangle PQR.

find lim as theta approach to 0 from the positive { A(theta) / B (theta) }

from f.p.'s cos(x + delt x/2).sin(delt x/2) all divided by delta x/2, making a complex fraction;
as delta x approaches zero, the numerator of sin() approaches zero, but so does the denominator, (delta x/2).
Why can that apparent problem be so easily ignored?

Solve the equation by completing the square.

-7x^2 - 10x + 3 = 0

x^2 - 3x - 15 = -5

x^2 - 17x = -10x - 6
