Answers:
Reason 2: Reflexive Property of Congruence
Reason 4: Hinge Theorem

----------------------------------------------

Explanation:

The reflexive property of congruence basically says that any angle is congruent to itself. Also, any segment is congruent to itself. It's a trivial thing to think about, but needed for this proof to work

The hinge theorem says that the larger the angles are, the larger the opposite side will be. Think of a door opening on a hinge. The larger the hinge angle, the further the door will be from the frame.

Please help me with this calculus 1 question
schepotkina [342]

Answer:

tangent: y- \frac{\pi }{4} = -4(x - \frac{\pi }{2})

Step-by-step explanation:

differentiating

y' sin(16x) + 16ycos(16x) = cos(2y) -2xy'sin(2y)

isolating y' to one side and simplifying

y'sin(16x) + 2xy'sin(2y) = cos(2y) - 16ycos(16x)

y'(sin(16x) + 2xsin(2y)) = cos(2y)-16ycos(16x)\\y' = \frac{cos(2y)-16ycos(16x)}{sin(16x) + 2xsin(2y)}

when x = \frac{\pi}{2},

y' = \frac{cos(\frac{\pi }{2} ) - 4\pi cos(8\pi)   }{sin(8\pi) + \pi sin(\frac{\pi }{2}) }

y' = \frac{0-4\pi }{0+\pi } = \frac{-4\pi }{\pi } =-4

tangent: y- \frac{\pi }{4} = -4(x - \frac{\pi }{2})
