Solve for x square root of 3sec(x)-2=0
Problem
Solution
Isolate the secant term by adding
2 to both sides of the equation.
Divide both sides by
√(,3) to solve forsec(x)
Convert the secant function to its reciprocal, the cosine function, using the identity
sec(x)=1/cos(x)
Determine the reference angle by finding the value of
x in the first quadrant where the cosine is√(,3)/2
Identify all solutions within the interval
[0,2*π) Since cosine is positive in the first and fourth quadrants, the solutions arex=π/6 andx=2*π−π/6=(11*π)/6
Generalize the solution by adding multiples of the period
2*π wheren is any integer.
