Find the Equation Using Slope-Intercept Form y=(4+csc(x))/(8-csc(x)) , (pi/6,1)

The given problem is asking for the equation of a line in slope-intercept form, which is y = mx + b, where 'm' is the slope of the line and 'b' is the y-intercept. The problem provides the general form of the equation y = (4 + csc(x)) / (8 - csc(x)), and a specific point that lies on the line, which is (pi/6, 1). We need to find the values of 'm' (slope) and 'b' (y-intercept) that will satisfy the given point. To do so, we might need to manipulate the provided equation and utilize the given point to calculate the slope and y-intercept, effectively re-expressing the equation in the desired slope-intercept form.

Solution:

Step:1

Determine the b value using the line equation formula.

Step:1.1

Employ the line equation y=mx+b to ascertain b.

Step:1.2

Insert the slope m into the equation: y=(4+csc(x)8csc(x))x+b.

Step:1.3

Plug in the x coordinate: y=(4+csc(π6)8csc(π6))π6+b.

Step:1.4

Input the y coordinate: 1=(4+csc(π6)8csc(π6))π6+b.

Step:1.5

Solve for b.

Step:1.5.1

Reformulate the equation: (4+csc(π6)8csc(π6))π6+b=1.

Step:1.5.2

Simplify the left-hand side.

Step:1.5.2.1

Break down each component.

Step:1.5.2.1.1

Condense the numerator.

Step:1.5.2.1.1.1

csc(π6) is exactly 2: 4+28csc(π6)π6+b=1.

Step:1.5.2.1.1.2

Combine 4 and 2: 68csc(π6)π6+b=1.

Step:1.5.2.1.2

Condense the denominator.

Step:1.5.2.1.2.1

csc(π6) is exactly 2: 682π6+b=1.

Step:1.5.2.1.2.2

Multiply 1 by 2: 682π6+b=1.

Step:1.5.2.1.2.3

Subtract 2 from 8: 66π6+b=1.

Step:1.5.2.1.3

Eliminate the common 6 factor.

Step:1.5.2.1.3.1

Remove the common factor: 66π6+b=1.

Step:1.5.2.1.3.2

Rephrase the equation: 1π6+b=1.

Step:1.5.2.1.4

Multiply 1 by π6: π6+b=1.

Step:1.5.3

Isolate b by subtracting π6 from both sides: b=1π6.

Step:2

With the slope m and y-intercept b identified, insert them into y=mx+b to derive the line's equation: y=x(4+csc(x))8csc(x)+1π6.

Step:3

The process is complete.

Knowledge Notes:

  1. Slope-Intercept Form: The slope-intercept form of a linear equation is y=mx+b, where m is the slope and b is the y-intercept.

  2. Cosecant Function: The cosecant (csc) is the reciprocal of the sine function. For an angle x, csc(x)=1sin(x). It is undefined when sin(x)=0.

  3. Simplifying Fractions: When simplifying fractions, any common factors in the numerator and denominator can be canceled out.

  4. Substitution: To find specific values of a function, substitute the known values of variables into the function.

  5. Solving for a Variable: To solve for a variable, isolate it on one side of the equation by performing inverse operations on both sides of the equation.

  6. Exact Values of Trigonometric Functions: Some angles have exact trigonometric values that can be used for simplification, such as csc(π6)=2.

  7. Linear Equations: A linear equation graphs as a straight line on the Cartesian plane and has a constant rate of change or slope.
