Solve for x 2sin(x)+ square root of 2=0
Problem
Solution
Isolate the sine term by subtracting
√(,2) from both sides of the equation.
Divide both sides by
2 to solve forsin(x)
Identify the reference angle by finding the value where
sin(θ)=√(,2)/2 which isπ/4 (or45 .
Determine the quadrants where the sine function is negative, which are Quadrant III and Quadrant IV.
Generalize the solution by adding multiples of the period
2*π to account for all possible values ofx wheren is an integer.
