X = sin 1/2θ, y = cos 1/2θ, −π ≤ θ ≤ π(a) eliminate the parameter to find a cartesian equation of the curve.

Roman55 [17]

First solve for theta in 'x' equation:
$\theta = 2 sin^{-1} x$

Substitute into 'y' equation:
$y = cos (\frac{2 sin^{-1} x}{2}) = cos (sin^{-1} x)$

Simplify by rewriting cos in terms of sine.
Using pythagorean identity: $sin^2 + cos^2 = 1$

$cos = \sqrt{1-sin^2} \\ \\ y = \sqrt{1-sin^2 (sin^{-1} x)}$
Simplify using inverse function property: $f(f^{-1} (x)) = x$

$y = \sqrt{1 - x^2}$

Answer:

x = 2, y= 3

Step-by-step explanation:

y = -2x+7

y = 5x-7

Since the equations are both equal to y, set them equal to each other

-2x+7 = 5x-7

Add 2x to each side

-2x+7 +2x= 5x+2x-7

7 = 7x -7

Add 7 to each side

7+7 = 7x

14 = 7x

Divide by 7

14/7 = 7x/7

2 = x

Now find y

y = 5x-7

y = 5*2 -7

y = 10-7

y =3

Answer:

The answer to your question is:

a) sin Ф = -3/√10

b) cos Ф = 1/√10

c) tan Ф = -3

Step-by-step explanation:

See the picture below

just remember

sin Ф = opposite / hypotenuse

cos Ф = adjacent / hypotenuse

tan Ф = opposite / hypotenuse
