Find the domain

Find the x -intercept/zero

y^{'} = 76 x^{3}

Evaluate

y = x^{2} \times 19 x^{2}

Simplify

More Steps

Evaluate

x^{2} \times 19 x^{2}

Multiply the terms with the same base by adding their exponents

x^{2 + 2} \times 19

Add the numbers

x^{4} \times 19

Use the commutative property to reorder the terms

19 x^{4}

y = 19 x^{4}

Take the derivative of both sides

y^{'} = \frac{d}{d x} (19 x^{4})

Use differentiation rule \frac{d}{d x} (c f (x)) = c \times \frac{d}{d x} (f (x))

y^{'} = 19 \times \frac{d}{d x} (x^{4})

Use \frac{d}{d x} x^{n} = n x^{n - 1} to find derivative

y^{'} = 19 \times 4 x^{3}

Solution

y^{'} = 76 x^{3}

Evaluate

y = x^{2} \times 19 x^{2}

Simplify

More Steps

Evaluate

x^{2} \times 19 x^{2}

Multiply the terms with the same base by adding their exponents

x^{2 + 2} \times 19

Add the numbers

x^{4} \times 19

Use the commutative property to reorder the terms

19 x^{4}

y = 19 x^{4}

Move the expression to the left side

y - 19 x^{4} = 0

To convert the equation to polar coordinates,substitute x for r cos (θ) and y for r sin (θ)

sin (θ) \times r - 19 (cos (θ) \times r)^{4} = 0

Factor the expression

- 19 cos^{4} (θ) \times r^{4} + sin (θ) \times r = 0

Factor the expression

r (- 19 cos^{4} (θ) \times r^{3} + sin (θ)) = 0

When the product of factors equals 0,at least one factor is 0

r = 0 - 19 cos^{4} (θ) \times r^{3} + sin (θ) = 0

More Steps

Factor the expression

- 19 cos^{4} (θ) \times r^{3} + sin (θ) = 0

Subtract the terms

- 19 cos^{4} (θ) \times r^{3} + sin (θ) - sin (θ) = 0 - sin (θ)

Evaluate

- 19 cos^{4} (θ) \times r^{3} = - sin (θ)

Divide the terms

r^{3} = \frac{sin ( θ )}{19 cos ^{4} ( θ )}
