Subtract the exponents of the corresponding variables.
y: 4-6 = -2
z: 3-2 - 1
Place the positive exponent of 1 as the numerator of the fraction. The negative exponent is placed as the denominator and switched to positive.
Final answer:
z/y^2
In words: z over y raised to the power of 2.
<u>Answer</u>
-3/√13
<u>Explanation</u>
We are going to take angle ∅ to be at the origin (point (0,0)).
The point at (-2, -3) means, 2 units to the left (negative side of x-axis) and 3 units downwards (negative side of y-xis).
This will make a right triangle with a hypotenuse of √(2²+3²) = √13
The angle ∅ is in the 3rd quadrant where cosine is negative.
cosine = adjacent/hypotenuse
The exact answer for cos ∅ = -2/√13
