Webwork, TrigEquations, Problem #5
Find the principal root of this equation:
Tan(x) – 1 = 0
Tan(x) – 1 = 0
+1 +1
Tan(x) = 1
(Tan-1 )Tan(x) = 1 (Tan-1 )
x = 45°
x = π/4
The Principal Root of this equation is π/4

Distance Formula, Midpoint and Circles, Perpendicular Bisector, Chapter 9, Section 9.1 Page 751, Question #5
Use the distance formula to find the distance between the two points. (6, 7) and (3, 2)
d = √ ( ( X2 – X1 )² + ( Y2 – Y1 )² )
d= √ ( ( 3 – 6 )² + ( 2 – 7 )² )
d= √ ( ( -3 )² + ( -5 )² )
d= √ ( 9 + 25 )
d= √ ( 34 )
Ladies and gentlemen, welcome to the main event. In the red corner, majoring in Architectural technology, she hails from Rzeszow, Poland, and was rated by many professors with a passing grade – with 52 wins, 38 of them coming by the way of knockouts, and only one failed class- future student of a physics course, and future architect, she is, undefeated in five college classes, current City Tech student, Julia Prokop.
