To solve the equation cos2x - sqrt 2 sinx = 1, rewrite cos2x as 2cos^2x - 1. Use the quadratic formula to solve for cosx. Substitute the values back into the equation cos2x - sqrt 2 sinx = 1 and solve for x.

To solve the equation cos2x - √2 sinx = 1, we can use trigonometric identities and equations. First, we can rewrite cos2x as 2cos^2x - 1. So, the equation becomes 2cos^2x - √2 sinx - 1 = 0. To solve this quadratic equation, let's set 2cos^2x - √2 sinx - 1 = 0 and solve for cosx.

Next, we can use the quadratic formula to solve for cosx. The quadratic formula states that x = (-b ± √(b^2 - 4ac)) / 2a. In this case, a = 2, b = -√2 sinx, and c = -1. Plugging in these values, we can solve for cosx.

After solving for cosx, we can substitute the values back into the equation cos2x - √2 sinx = 1 and solve for x. The student's question is about solving the equation cos(2x) - √2 sin(x) = 1 for all solutions. We can use the trigonometric identities cos(2x) = 1 - 2sin2(x) or cos(2x) = 2cos2(x) - 1 to rewrite the equation. Since we have a sine term in the original equation, let's use the former identity:

cos(2x) - √2 sin(x) = 1

(1 - 2sin2(x)) - √2 sin(x) = 1

2sin2(x) + √2 sin(x) - 1 = 0

This is a quadratic equation in sin(x).

We can solve this quadratic equation for sin(x), then find x using inverse trigonometric functions. By factoring the quadratic or using the quadratic formula, we get solutions for sin(x). Then, we solve for x by considering all possible angles in the unit circle that correspond to the found sine values.

The equation cos(2x) - √2 sin(x) = 1 can be solved by using trigonometric identities to simplify and factor the equation, leading to solving for sin(x) using inverse operations.

The original equation given is cos(2x) - √2 sin(x) = 1. To solve this equation, we can use trigonometric identities to simplify the cosine term. One such identity is cos(2x) = 1 - 2sin²(x), which allows us to rewrite the equation as 1 - 2sin²(x) - √2 sin(x) = 1. From there, we subtract 1 from both sides, thus isolating the sine terms on the left: - 2sin²(x) - √2 sin(x) = 0. Factoring out the common term sin(x), we get sin(x)(-2sin(x) - √2) = 0. Setting each factor equal to zero gives us two possible solutions: sin(x) = 0 and sin(x) = -√2/2. In the context of a right triangle, these solutions correspond to specific angles where the sine value is 0 and -√2/2, respectively. The solutions can be found using standard trigonometric unit circle values or by calculating the inverse sine for -√2/2.

The value of the solution is, 3 is 1 percent of 300.

We have to give that,

To find the amount for 1 percent is 3.

Let us assume that,

3 is 1 percent of x.

Hence, It can be written as,

3 = 1% of x

Solve for x,

3 = 1/100 × x

3 × 100 = x

x = 300

Therefore,  3 is 1 percent of 300.

The slope of the line tangent to the curve y^2 + (xy+1)^3 = 0 at (2, -1) is -3/4.

The slope of the line tangent to the curve y^2 + (xy+1)^3 = 0 at (2, -1) can be found using the concept of implicit differentiation. To find the slope, we need to differentiate the equation with respect to x and then substitute the coordinates (2, -1) into the resulting equation. Let's solve it step by step.

First, we differentiate the equation implicitly with respect to x:

2y * dy/dx + 3(xy + 1)^2 * (y + x * dy/dx) = 0

Next, we substitute the values x = 2 and y = -1 into the equation:

2(-1) * dy/dx + 3(2(-1) + 1)^2 * (-1 + 2 * dy/dx) = 0

Simplifying the equation:

-2dy/dx - 3 * 1 * (-1 + 2dy/dx) = 0

-2dy/dx + 3 + 6dy/dx = 0

Combining like terms:

4dy/dx = -3

Finally, solving for dy/dx, we get:

dy/dx = -3/4

The slope of the tangent line to the curve at the point \((2, -1)\) is:

[tex]\[\boxed{\frac{3}{4}}\][/tex]

To find the slope of the tangent line to the curve given by the equation [tex]\( y^2 + (xy + 1)^3 = 0 \)[/tex] at the point [tex]\( (2, -1) \)[/tex], we need to use implicit differentiation.

Given the curve:

[tex]\[y^2 + (xy + 1)^3 = 0\][/tex]

We differentiate both sides with respect to x . Using the chain rule and implicit differentiation, we get:

[tex]\[\frac{d}{dx} [y^2] + \frac{d}{dx} [(xy + 1)^3] = 0\][/tex]

First, differentiate [tex]\( y^2 \):[/tex]

[tex]\[\frac{d}{dx} [y^2] = 2y \frac{dy}{dx}\][/tex]

Next, differentiate [tex]\( (xy + 1)^3 \)[/tex] using the chain rule:

[tex]\[\frac{d}{dx} [(xy + 1)^3] = 3(xy + 1)^2 \cdot \frac{d}{dx} [xy + 1]\]\[= 3(xy + 1)^2 \cdot (y + x \frac{dy}{dx})\][/tex]

Putting it all together, we get:

[tex]\[2y \frac{dy}{dx} + 3(xy + 1)^2 (y + x \frac{dy}{dx}) = 0\][/tex]

Now, substitute [tex]\( x = 2 \) and \( y = -1 \)[/tex] into the equation:

[tex]\[2(-1) \frac{dy}{dx} + 3((2)(-1) + 1)^2 \left( -1 + 2 \frac{dy}{dx} \right) = 0\]\[-2 \frac{dy}{dx} + 3(-2 + 1)^2 \left( -1 + 2 \frac{dy}{dx} \right) = 0\][/tex]

[tex]\[-2 \frac{dy}{dx} + 3(-1)^2 \left( -1 + 2 \frac{dy}{dx} \right) = 0\]\[-2 \frac{dy}{dx} + 3(1) \left( -1 + 2 \frac{dy}{dx} \right) = 0\][/tex]

[tex]\[-2 \frac{dy}{dx} + 3(-1 + 2 \frac{dy}{dx}) = 0\]\[-2 \frac{dy}{dx} + 3(-1 + 2 \frac{dy}{dx}) = 0\][/tex]

[tex]\[-2 \frac{dy}{dx} + 3(-1) + 6 \frac{dy}{dx} = 0\][/tex]

[tex]\[-2 \frac{dy}{dx} - 3 + 6 \frac{dy}{dx} = 0\][/tex]

[tex]\[4 \frac{dy}{dx} - 3 = 0\][/tex]

[tex]\[4 \frac{dy}{dx} = 3\][/tex]

[tex]\[\frac{dy}{dx} = \frac{3}{4}\][/tex]

So, the slope of the tangent line to the curve at the point \((2, -1)\) is:
