Check that your solutions to part (a) and (b) are consistent by substituting the expression for y into your solution for part (a). 9x^2 - y^2 = 1

Step-by-step explanation:

The question is incomplete. Find the complete question in the attached file.

a) Given the expression 9x^2 - y^2 = 1

Differentiating implicitly will give;

We can then make dy/dx the subject of the formula as shown;

b) In order to solve the question explicitly, we will first have to make x the subject of the formula before differentiating.

Using chain rule to solve the equation;

let;

du/dx = 18x

dy/du =

dy/dx = dy/du * du/dx

dy/dx =

c) In order to confrim that solutions to part (a) and (b) are consistent, we will substitute into the answer in (a) as shown;

From (a)

This shows that they are consistent

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
