Which of the following gives the Cartesian form of the equation? Equation:

Answer Choices:
a)
b)
c)
d)

C

Step-by-step explanation:

In a trigonomitrical circle

● cos x => x

● sin x => y

So

● sin x /(cos^2 x - sin^2 x) = y/y^2-x^2

A cartesian from start with y=

So y = x^2 -y^2

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

answer: 20
